Each SM component has its own quirks.  For warp closers, the answer to your quiestion is maybe.  If it started on a WP, you could close the WP and then queue a move after that.  If it didn't start on a WP, you couldn't give the order to move to the WP and then close on the same turn.  The SM order button won't light up.  I think that if a WP closer starts on 
any WP, it can be ordered to move to another WP and close it, though...
