Yes, there can be displacement even if no force acts on an object.
According to Newton's First Law of Motion, an object in motion continues to move with a constant velocity in a straight line unless acted upon by an external force. So, if an object is already moving, it can be displaced without any additional force. However, a force is needed to change its velocity (i.e., to accelerate or decelerate it).
Example: A hockey puck sliding on a frictionless ice surface keeps moving and is displaced without any applied force.
