Simple answer - No

Whole answer - This is fly by wire. There is no mechanical/hydraulic linkage between the stick and the control surface. Think of your computer and a wireless mouse. If your computer crashes no amount of moving your mouse is going to do anything to the computer.

Ok fine. But the horizontal stabilizer is still hydraulically operated whether the auto pilot or the pilot sends the signal to move. And I am guessing that hydraulic rams that operate the stabilizer can over come the trim tab. LOL.

Or is there really a trim tab at all? Maybe the whole stabilizer is used to trim and there is no separate trim tab at all? If so then that is f'd IMO.
