But if we did use quSDajvo' instead of quSDajDaq, would the meaning be that the enemy commander sits at his chair, and from there he is caused to go to prison ?

No. -vo' involves motion away from something, even if that motion is just your line of sight. There is no motion or direction involved in being in your chair when you issue an order to put someone in prison. That happens at your chair or in your chair or on your chair in Klingon, not from your chair.
