It's exceedingly unlikely that the TiBook has a drive taller than 9.5mm -- even my old PowerBook G3 came with a 9.5mm drive.
Assuming you're running Mac OS X on the TiBook, and it's current, you should have no trouble. Just make sure that the version of Mac OS X installed on the TiBook's drive (before the swap) is at least as recent as the version the AlBook shipped with.
