I seems to remember hearing of this, but I can't prove it (wish I had my DEC
catalogs in front of me).  Off hand you're going to have problems since the ROMS
on TC boards are in MIPS code and I don't think VAX ever made allowances for MIPS
code like they did for the Alpha DS3000.
(Yes, the DEC Station 3000 had some magic MIPS boot emulation code so they could
initalize TC boards)

So unless you have a VAX with a MIPS emulator, TC cards with ROMS written for a
VAXstation or a kernel with TC support for your TC card, it's probably not
happening.  Though there's nothing from stopping you from trying!

Wouldn't have a TC pin out, would you?
