Does mv on a FAT filesystem actually rename or does it copy and delete?

one would hope that the kernel abstracts the filesystem layer enough
that a command like mv works the same everywhere, regardless of the
underlying filesystem ;)

i.e. the kernel should manage that on a lower layer without you having
to care (an mv on the same filesystem should always just modify the
(directory) metadata for the file, not the payload data itself)
