Well mtools act directly on an FAT filesystem and do not use the vfat/
msdos filesystem drivers in Linux. It has the "mren" command to rename
files.

However I still assume that this FAT filesystem is just corrupted and
that maybe not even mtools is able to do the rename.

What I'd do is:

First copy the whole block device with the filesystem block by block into
a file. Then make a copy of that file. Only work from the copy of the file.

Then you can throw 'mren', 'fsck.vfat' / 'fsck.msdos', use a hex editor,
or well just 'photorec' on it. And due to working with a copy of the
copy you have unlimited attempts.
