Unless Merlin were trapped in a yet unknown/unmentioned realm that is not the Mysthaven/Arendelle/Camelot. We don't know yet where Merlin is. We know he is NOT in Storybrooke (even though he does have a mansion there). We highly suspect that he is not in the EF (due to the smoky cloud conversation). But other than that, we don't have any real information.

And, as I recall from the finale, the Apprentice said to FIND Merlin, meaning that possibly even HE does not know where Merlin is situated.

Based on what we have seen (Lancelot in season 2, Excalibur and Mage reference in Season 3, and direct Camelot reference in Season 4), my money is on Camelot being another land in the EF like Mysthaven and Arendelle. And my money is also on the liklihood that Merlin is NOT in Camelot at the present time.
