This might indeed be a possibility. I have no experience with the A340 but on the MD-11, if during an engine run the AOA vanes stand in a high alpha position and due to some reason (e.g. the upper torque link being disconnected and hanging down, thus putting the NLG air/ground switch into "flight" position) the air ground system gets put into air mode, the stall protection system will activate, extend all leading edge devices and autothrottle will push all throttles to full power.
