Unless you view the turret as being at the forward edge of the tank, the hull will potentially block hitting the turret from a lower elevation. If the distance from the front of the turret to the front edge of the hull is equal to the height of the turret, then the turret can't be hit by a vertical angle greater than 45 degrees. Between 0 and 45 degrees some angles will be unavailable because of the height differences between firer and target, e.g. for 0 degrees to be available firer and target would have to be the same height. The larger the height difference between them, the smaller the available range of angles. But in any case where the turret can be be hit, the hull can be hit as well.
