As it stands, the game can be played and enjoyed by many ages. Ultimately, the player is in charge of how age-appropriate the game plays. We have to remember that some adults still want to play an "innocent" game, while some teens will cry out of more mature-themed content. The Sims 4 is fairly easily modded and with good reason, I believe, so that people can create a more personalized game.
So, to answer the questioning topic title - no, I think the current game is playable by so many age groups that a slight tip in one direction would immediately show as a negative in EA's wallet.
