Yes. Even easier. For example with Mac OS X you just doubleclick the label and type the new name.

There is nothing for the OS to remember. The filesystem has been relabeled, of course the new name will appear. This works with every OS that has USB, massstorage and FAT support.
I dont find double-clicking the labelname particularly intuitive, and looking from the accidently renamed files/volumes I find on other people's macs, it's not really usefull.
Anyhow... what I really like with amiga systems, is that you can remove a device with programs still open on it, the OS wont panick, nor will it kill the programs or anything other nasty stuff. It will just ask the user to insert the disk/whatever when needed, recognise it and move on. Try that with windows, OSX, linux etc.
