Being able to talk in Latin with friends, and not being able to tell where you live or where you'd like to go on holiday, is not so magic, it would rather prevent to use the language to talk nowadays. Yes, some people make Latin club to talk in Latin like a living language, and it's so fun!
Honestly, I wouldn't worry about it all that much. You won't learn all that much Latin from Duolingo and will have to continue elsewhere so there will be plenty of time for magic later.
In any case, Eboracum was Roman city, so if you go to York, and happen to time travel to the Roman era, you will be able to discuss its name in Latin.
