The only case that I know of where a filesystem is case-insensitive,
but not case-preserving, is that of DOS FAT16 filesystems, and the
MSDOS port of Emacs already considers renaming a file in such a case
as a no-op that should not trigger an error. So I think we can safely
ignore this hypothetical situation until someone actually describes
it.
