If you go in to the booking on AA.com using the AA PNR (i.e. the one shown when you are selecting seats on ba.com) you can add your KTN at the bottom in the passenger details area.
If you want to change the frequent flyer number associated with the booking then you need to use the finnair MMB with the BA PNR, take out your BA number, give it a few minutes, then add in your AA number.
