Exactly right, aquaplaning happens at speeds from about 80 km/h upwards. The physics of this have absolutely nothing to do with 2WD or 4WD.

Once the car floats (on the water layer) it floats. You can only hope to get grip back because you're leaving the puddle, or the car slows down below the dangerous speed. (Or nothing is in the way in the direction where physics take your car)
