Yes. Look into a VM feature called Common System Extensions (CSE). It
takes some planning to do this, but as long as both VM systems can
directly share disks, that's exactly what CSE was designed to do.
DIRMAINT has support for syncing user directories in CSE complexes, and
if the directory is not on the IPL volume, you can share it between
systems.

Warning: this is NOT trivial to set up. It is also not very well
documented any longer -- the information is there, but is scattered.
There is some discussion of CSE in the CP Planning manual, but you would
be well advised to find a copy of Alan Altmark and John Fransicovich's
recent presentation on VM clustering techniques from the z/VM Expo or
WAVV to explain in more detail what is involved.
