Having (or lacking) religious beliefs can be quite personal for some people; therefore, I don't think it's something that should ever be lied about under normal circumstances. It's kind of like discussing politics... either be honest about what you believe, or say "I don't want to talk about it", "I don't feel comfortable expressing my opinions", etc. I'm Christian, and my boyfriend is not (not sure if you could call him an atheist or agnostic). I don't tell my other Christian friends that he doesn't believe in God, but I certainly don't lie and say he does, either. It's simply not something we discuss, and they are free to draw whatever conclusions they'd like to.
