Yes.
Consider the case where both objects are moving in the same direction on the same path, the more massive one at a speed of 1, and the smaller one behind it and overtaking it with a speed of 4. After the collision, conserving momentum and kinetic energy, the small object will be motionless, and the large object will have accelerated to a speed of 3. (Both before and after, total momentum is 6, total kinetic energy 9.)
