I don't think so. If you keep all of your boarding passes for that direction of your flight together and wave them all at the gate keeper, you might be able to get away with it.

My experience with the gatekeepers is that they can be persnickety at times.

My last BE flight (award ticket CVG-CPT via JFK) I tried to use the BE lounge at CVG. The gatekeeper had to make three calls (AFTER looking at my boarding passes) to determine whether I could be allowed in.

But then CVG's BE lounge only operates for the CDG and LGW flights that leave around 7 pm and I was nosing around there at 3.
