No, you always mount the filesystems under the same names in Linux, but
that moves the problem to the grub configuration and /etc/fstab where
you tell it what partitions to mount. Auto-detected labels on
filesystems that support them are supposed to solve this problem, but a
default install puts the same labels on every installation so as soon as
you try to move and re-use some drives the problem is even worse.
Especially when one clones a drive:
dd if=/dev/hda of=/dev/hde
as I've done. It was a problem with RHL 7.x or so when RH introduced
labels, and nothing's been done about it that I've noticed.
As far back as, I think it was 1971 with IBM's OS, (I'm referring to my
memory, not when this started), if the operating systems found two
volumes[1][2] with the same label[3], it would ask what to do (during
IPL aka boot) or reject the newer (later).
[1] Disk or tape
[2] One volume, one filesystem.
OS labels (it's z/OS these days) volumes whereas Linux labels
filesystems. It's not quite the same, to label a disk volume under
Linux, one would write it to the MBR or other space outside the
partition/filesystem.
