I think naming is always a quest:) To me it has to be meaningful but the final state is just a developers preference. You like one why I like the other. In this case being a brand new developer to the project `is_code_relevant_for_linter` tells me more than `is_linter_active` but again - it is personal taste. If you are owner or core developer for this or that product I am willing to follow your rules ;]
