Yes, I noticed how stupid the question is after posting. 🙂

Yes. Black has no last move again - it cannot have been b7-b6 or e7-e6 because Black's Bishops are already missing, and they have been captured by the white pawns to double them.
I think Black's last move was -1...c2-c1=R which makes the bRc1 the bPh7, capturing five units on its way on the white squares, RBNNQ. The DSB can't have been captured on this road. White is allowed to add one piece, the DSB.
