Not only that, but there’s a difference between copyright and trademark. A name alone isn’t really copyrightable, especially not if its then used in a wildly different context.

If you build a car you can’t name it Mickey Mouse (not using any of the art, typography or anything else from Disney), not because of copyright, but because Disney holds a trademark for that name.
In trademark law, prior usage by someone else doesn’t work like in patent law. In patent law it makes the patent invalid. In trademark law it only means that the other user that’s been using the trademark before the trademark was established is allowed to continue using it, but the trademark is not invalidated.
So the Tolkien Estate can continue to use the name Anduil, and Anduil the company cannot go after them, but the Tolkien Estate can also not stop Anduil the company to use that name.
