Trademark law prohibits you from making a buck off another guy's trademark; it does NOT require you to change comments in code you don't distribute. There's an old example from the computer industry: DEC used to sell computers under the trademark VAX, while another company (Danish, if I remember correctly) sold vacuum cleaners under the same name. There was no trademark conflict because no one in his right mind is going to confuse a VAX vacuum with a VAX computer. A quick pair of letters (one from DEC disclaiming any interest in selling vacuums, and one from VAX disclaiming any plans to sell computers) and the problem went away. Linus' trademark means is that no one can sell software under the name Linux(R) without his permission, and that's all it means. And in reference to his enforcing the trademark, if he doesn't then he loses it.
