IS an AA booking isn't it ??
And I think what you're asking is if AA will know you ditch the final sector of your itinerary, LHR DUB, operated by BA.
I'm sure they can find out, if they wish to. AA is rumoured to have a more robust approach to encouraging passengers to complete their journey as ticketed: but I doubt this would extend to persuading BA to strip you of your BAEC status.
