If they're laptops, I'm not clear what this means. You can certainly
have the /home folder physically reside on one of them, and use an NFS
mount so the other one can use it as its own /home. But both laptops
have to be powered one, and they would need to be powered on in a known
sequence (provider first, then consumer). Can you explain a bit more
about how you'd like to share a disk if one of the laptops is not running.

Right. But they're both on the same physical machine, right?

Yes, there shouldn't be any problem: nothing of the OS lives in /home,
only user account directories. However, if the different Linux flavours
mean some applications are installed in different versions between the
two machines, then their config or resource files probably can't be
shared, as there will be syntactic or resource differences which one
version will understand and the other not; these files typically live in
/home/<username>/.something, or in a window-manager subdirectory.

You seem to be describing the sharing of the /home partition between
multiple-boot (or concurrent VM) instances of Linux /on the same
machine/. You said at the top you have two laptops. Did you want them to
share one /home between them, or for each one to host two OSs?
