Improved the question following Dimitrov's comment.
Jul 13, 2017 at 0:29 comment added Bobby Grizzard Of course I should have thought about that, thank you. Is it possible the question is interesting if we insist that $\mu_n \in K$? I will edit my question.

Jul 12, 2017 at 18:36 comment added Vesselin Dimitrov No, because such an extension need not contain the $n$-th roots of unity (whereas $\mu_n \subset \mathbb{Q}(E[n])$ by the Weil pairing, and you may evidently not have a proper containment $K \subsetneq \mathbb{Q}(E[n])$).
