There is definitely something implied in the first episode seeing as Anna hopped on a ship to go to Mist Haven (EF), which appears to show that place is in close proximity to Arendelle. If it were a separate world, she'd need some kind of magic travelling device (something to make a portal) to reach Mist Haven. However, for the time being, I still believe we don't know enough confirmed facts to change things on the wiki just yet. We could learn new things, that we currently don't know with absolute certainty about, in the next few episodes concerning where Arendelle is situated. It could prove the theory of the EF being within a world rather than the EF being a world itself, or it could not.
