Well, the EZE Centurion lounge, folks were very nice about it then; I told them I did not have my "real" AMEX Platinum card on me, and of course, they should have technically denied me admission. (I also suspect using Spanish and being aware of cultural norms made a difference.)
I still have no idea if MEX AMEX C lounge allows HHonors AMEX "Platinum" - but I do know they admit AMEX Gold, as I have seen it many times.
I have had an AC membership for a long time and am ow Emerald, so AA would have been no problem, as I was departing on AA to JFK.
