His Timelines toy bio seems to suggest so and so does the BW prequel comic Dawn of Future's Past. Basically they say after the Great War Razorclaw formed his own faction, The Predacons, and started a new war and was on the verge of defeating the Autobots/Maximals before he was betrayed and assassinated by the Tripredacus Council, but was this ever made canon? I always assumed the Tripredacus Council were the original Predacon founders in the cartoon... The way they were portrayed all shadey and mysterious. Was Razorclaw ever mentioned in the show? I haven't watched it in so long it's hard to remember.
