No because "Mu" is an experience, not an idea. :) All zen koans point away from ideas and to an indescribable experience. That is why they appear "kinda weird" but they actually aren't. :)
There is no one right answer to the "proper" understanding of and use of Koans. It is different from school to school in Zen Buddhism, and no one school has the copyright on "Koan". So there is room to explore here.
