NO,
It does not HAVE force.
Actually nothing (a body) ever HAS force.
So a train or a stone or a man moving with a constant speed or accelerating or decelerating … none of them HAVE force.
A force is always applied by one body on another body.
All moving bodies have Momentum. Since a movement is always relative you have to talk about a reference frame if we have to quantify that momentum.
The difference between a body moving at a constant speed (velocity would be a better term) and another body which is moving but not at a constant velocity is that it requires / exerts Force on another body. But that body is always another body And the force is exerted but not POSSESED ( as in have).
The above is based on a precise Physics Terminology simplified for laymen.
In common English we use the terms as used in the question but it is wrong.
