Probably not.

Getting VMS compilers, VMS language RTL, VMS RTL,
RMS, VMS system services and DCL working on Linux
in a fully compatible manner would be very tricky.

Getting something sort of VMSish up and running
may be easier. In fact I believe there are companies
selling such products already. But they have not
taken away the VMS market.
