Yes, I've done this before. In fact, my flights weren't even on the same PNR for the connection. Per OW rules, when making a long-haul to short-haul connection (with both flights on OW airlines) then the long-haul flight class of service will govern the lounge access during the connection regardless of the short-haul class of service.
What you will not have is access to the BA CCR; one must fly BA F for that.
