Sure, but that's assuming the plane was trimmed somewhat correctly to start with. The only reason the pilots had problems manually moving the trim was because the electric motor moved it far out of the correct trim range. Also, it's not zero power. A ram air turbine deploys and provides hydraulic pressure to move the controls. And there are batteries to keep a small number of essential flight instruments powered.
