Sure. You can submit batchjobs on remote DECnet machines.
I don't remember the syntax under VMS, but under RSX you basically do:

NFT node::filename/SB (MCR)
SUB node::filename/REMOTE (DCL)

Note that the filename needs to be on the remote machine. If you want to 
submit a batch job where the file is on you local machine, you should 
transfer the file first, and then submit it on the remote machine.

As for doing it from Unix, I guess that depends on whether you Unix 
system have DECnet.

Yes.
