Yes.  I've done it many times.

This is a little wierd.  Is there something more you might tell us about
your setup?  It's not at all typical to have a CDROM drive as the master
of the primary IDE channel (i.e., as /dev/hda).  I also have no idea what
Nand or nanda1 mean: can you clarify?  Where do you have DOS installed
(i.e., which drive on which IDE channel)?

I don't think a vfat filesystem can be put on a CD.  They're usually
iso9660.  That said, I usually don't supply any "-t filesystem" argument
when I mount a CD.  Rather, I just do mount /dev/hdx /where/uwannamount.
Provided you haven't already amounted something at the mount point in
question (in your example /mnt), this should work just fine.  I'd say try
it without specifying the filesystem type (vfat is almost surely wrong for
a CD drive) and see if that gets it mounted.
