No. When you have a registered trademark, you do not (contrary to what you might believe if you read most Internet forums) "own" the word; you have only registered your usage of the word in a specific field, which allows you to make it easier to prove in court that someone else is being confusingly similar to you in their conduct of business.

However, for most people, their business is small and focussed, so usages of the same name in other fields would not be defendable against someone using it for adult entertainment production. This would be exceptionally difficult an acronym such as "npr", especially as it has been used for many things in the past (such as Northern Pacific Railroad, although Nevada Public Radio is a more interesting example).

(edit: After posting this I noticed I had had the tab open long enough that some other people responded with similar commentary, but I'm going to leave this up as I think it has a slightly different character, as well as a funny example.)
