No, you don't subtract any weight from gross when determining wing loading. Carried to the extreme, the airspeed can drop so low that the wing reaches its maximum possible CL, it is now at its stalling angle of attack and any attempt to further divert the passing airflow will cause the flow to start separating from the wings upper surface initiating a stall.
