Could the Tolkien Estate conceivably sue companies like Palantir and Mithril for misrepresenting Tolkien's works?

DISCLAIMER: THIS IS A HYPOTHETICAL LEGAL DISCUSSION regarding the works of Tolkien and use of his IP in corporate, for-profit business. Please, please, please don't make this political - I want to actually get responses.

Since this is a hypothetical, let's first assume that whoever currently controls the LOTR IP (I'm not sure who that would be honestly) believes that the actions of a specific company named after a concept created in LotR go against the very spirit and message of Tolkien's works.

Would they conceivably be able to sue a company like Palantir or Mithril for use of the IP in their name? Or is that too tenuous?
