If I'm not mistaken, this is checkmate.
The f7/B knight cannot be captured by any Black piece on Board B.
It is impossible to escape check by interposing when the checking piece is a knight.
The Black king cannot move to e8 because of the black rook (before teleportation), to e7 or c7 because of the d5 white knight (after teleportation), to d7 because of the c6 white bishop (before teleportation), or to c8 because of the black bishop (after teleportation).
