Yes: It happens to me all the time. Most likely it is from the tension you hold in your neck and shoulders while you are "thinking hard" that triggers the headache. Mental fatigue doesn't cause pain necessarily but it does lead to poor posture, tension and poor eating all of which can contribute to the problem.
