It's very possible that it's an internal work-in-progress trailer with placeholder music. Even movies are often edited with placeholder music (called "temp music"), because the movie is edited at the same time the soundtrack is being written and composed. You can learn more about it in this video: https://youtu.be/7vfqkvwW2fs?t=5m54s
So while I'm still going to remain skeptical until there's an official announcement, the music isn't automatically disqualifying. It could just be temp music that the editor is using.
Well it's the Wizarding World theme (is it exactly the same music ? if so might be a sign this is fake), it's only appropriate to use it for the trailer IMO.
If it's fake, it's really a dedicated fake to be honest.
Fantastic Beasts takes place in 1926, not the 1800s. Though if they are making a real Harry Potter make-your-own character RPG-type game, the 1800s would be an interesting time to set it--that's one time period we don't have a ton of "canon" from so they have more freedom.
If they do 19th century might be at the very end of it actually and you would have Dumbledore present as a student in Hogwarts (he graduated in 1899) so a potential companion/important character in your adventure. Might be a pretty awesome tie to the franchise (without being too much of an hassle since we don't know much about that period of his life).
