Not really. You're thinking about IR guided missiles hitting fighter jets. Realistically a radar guided SAM would hit the aircraft from the front or below. Not collide with the stabilizer from above and not explode. The damage is rather evidently indicative of a collision. Possibly part of an untimely separation and then having the lower aircraft "cut" the top aircraft, if that ripped open the fuselage or wing, game over.
Missile damage looks different, we've seen footage of what it looks like when the Azerbaijani passenger plane got shot down over Ukraine like 1-2 years ago.
Furthermore, given the intensity of aerial refueling and immense fatigue, accidents have a sharp increase with regards to how likely they are to occure. Quite frankly, it's also just more plausible than the idea of some Iraqi Luke Skywalker striking the death star so to speak. Given what we've seen, if you really want to hold on to the idea of the aircraft being shot at, it would be more likely that it's an accident that occured as part of an unwanted seperation because they aircraft had to conduct evasive maneuvers. But so far there is no evidence for that.
