Narrative:
Captain/PF (pilot flying) requested 2000 ft. Be selected in altimeter for the departure. After takeoff and climbing through 1000 ft.; PF requested autopilot to be engaged. After engaging autopilot and approaching 1500 ft.; I (pilot monitoring) noticed that the climb rate was not decreasing and we would break the mandatory crossing restriction. I then noticed that VNAV was not armed for the climb in order to capture 1500 ft. I notified PF of the climb above 1500 and also noticed he was fighting with the controls. I then noticed the trim had been at full nose up; notified PF of this and he disconnected the autopilot and manually trimmed the pressure off and hand flew from that point on. For a brief moment I saw a cas message that included '...trim...' but was distracted by ATC and when I looked back for the cas message it had disappeared. After brief discussion; we both agreed that advising ATC and returning to [departure airport] was the best idea.
