It's not really possible for someone to do better than guess that they are the same. I see similarities, but they may be very different
projections making it difficult to claim that they are the same.
Firstly, yes IT IS possible to do better than guess. Both maps are delineated with longitude and latitude. What more does a person need?
Secondly, they are indeed—not ‘may be’— very different projections, but again with longitude and latitude clearly marked throughout the map, I
and many others would have little difficulty discerning that the two maps
share virtually the same depiction of a southern continent.
Like I said before, there are some striking errors in the map such as the location of Zanzibar and the fact that Magellan's voyage should have
sailed through the continent as indicated on the map.
You seem fixated on errors such as Zanzibar and little interested in the SIGNIFICANCE of how they came to be. The Piri Reis map, which some here are
likely familiar with, goes out of its way to acknowledge that many portions of the map were borrowed from much earlier maps including errors worse
than Finé's similarly borrowed positioning of Zanzibar. This sets a precedent for Schöner’s 1524 world globe, allowing that he similarly
referenced older maps for his designs. I am only positing the likelihood that he had at his disposal an ancient map of Antarctica.
And just to be clear, Magellan did not sail to or ‘through’ Antarctica and I would never suggest that he did. His voyage is logged in full and we
know pretty well the course he traveled.
Magellan sailed through the strait that now bears his name. Upon receiving word of Magellan’s discovery, cartographers attempted to portray the
southern coast of the strait, but without knowledge of the southern landmass’ full size, cartographers like Schöner were left to their own devices
to determine how to render it. As I said before, I believe Schöner may have been overwhelmed by a map of Antarctica that possessed the very two
features discovered by Magellan, a prominent bay and two islands grouped together, and scaled the map to his globe convinced he had discovered the
missing piece of the puzzle.
Also, I see some differences between the map and the reconstruction you have produced. You seem to have done much more than simply remap
coordinates since the maps would not overlay. You have changed the size of the continent indicated on the old map.
Below is a likeness of the continent copied DIRECTLY from Schöner’s 1524 globe by Charles Hapgood and displayed on page 85 of his book Maps of the
Ancient Sea Kings, 1996.ed. and below it my polar projection of Finé’s map sans latitudinal/longitudinal delineations.

Hopefully comparing these two renderings will help you realize that your accusation that I did “MUCH more than simply remap coordinates
the Finé rendering is a bit over the top. The only thing I can do beyond this is ask you to make your own polar projection of Finé's map and then
let us compare. You can snag a polar grid from this website
As for “changing the size of the continent,” as already stated many times, Schöner and Finé clearly overscaled the map in error so I’ve
resized both modern Antarctica and Finé’s Antarctica to similar sizes for comparative purposes.
