In normal law, yes. At the lift ceiling the AoA is equal to alpha-max in 1g flight. In normal law the airplane will not exceed alpha-max with the sidestick on the aft stop and hence the lift ceiling is the maximum altitude attainable in 1g flight (unless the propulsive ceiling is more limiting).
In alternate law without high-AoA protection the lift ceiling marks the onset of perceptible buffeting in 1g flight. Exceedence of the lift ceiling results in increasing intensity of buffet and ultimately stall. There is no direct relation between lift ceiling and pitch control.
