It's highly unlikely that Disney would risk putting Poe and Finn in a romantic relationship. It would have to be extremely subtle and open to interpretation. Disney is already nervous about protecting their brand and this would be an almost absurd risk especially in foreign markets.
Well they shot a brief kiss with Mr. Sulu in Star Trek Beyond that Cho claims was cut. Star Wars is a bit more kids/family than Star Trek so unlikely you'd see much in SW anyway. Even the Han/Leia stuff in ESB would probably be a bit much in a Disney family film these days.
It is a bit surprising, but it certainly seems to be more legit than internet nonsense, but I guess who really knows. There was some joking around about Finn wearing Poe's jacket when TFA came out, but there are quotes from pretty major people in fairly major papers. But these days hoaxes can get going so easily and even mainstream media can get taken.
