IIRC, a 2007 macbook pro uses the PowerPC architecture, which OSX 10.6 is incompatible with. The 10.5 should work with it, but you may need a version
specific to PPC.
Edit: Also, you most likely wouldn't have to install 10.5 first before installing 10.6 if he has compatible hardware.
Dunno why you'd want to use a mac anyways
