I see no reason, in principle, why not. If knowledge were not possible without emotion, then no emotionless computer could achieve knowledge, which would come as a shock to the proponents of artificial intelligence (AI). Nor do I see anything in the concept of knowledge itself that rules out knowledge based on reason alone without any emotional content or associations. I don't mean to say that emotion can't play an essential role in some kinds of knowledge, only that I can't see how emotion would be essential to every kind of knowledge.

Is it possible for someone to produce knowledge simply based on reason alone, without any emotion?
