Not really, The Klingons and the Federation had been in a temporal war with the Federation starting in 2151. Many of the Temporal Wars had originated in the 32nd century which Klingon operatives would also have been able to track. The Klingon's are very much needed in Discovery and could emerge out of nowhere from 2151 to the Camp Khitomer Accords seeking vengeance.They already have been a part of Discovery. Zero reason to have them now.
