Choke chains are constructed such that pulling it results in pressure distributed around the dog's neck, but the muscles that absorb the pressure are situated mostly at the sides of the neck. The neck and throat are almost unprotected.
Choke chains can be dangerous. For many years I and others have criticized the use of choke chains and training methods that use jerking and pulling on a leash as a means of controlling behavior. Unfortunately, most dog trainers use just this technique. There is probably a relationship between the force of the jerk and the risk of injury. I believe dog owners should be warned that chaining a dog to anything firm, that isn't elastic, without surveillance may increase the risk of a spinal injury. A dog can easily forget the boundaries of the chain or rope, accelerate, and suddenly come to a halt, with all the stopping power concentrated around the dog's neck.

I don't like seeing dogs strung up on their leads, and the Borzoi moved beautifully and lightly on a loose lead beside his handler, unlike many other dogs at crufts.
However the above basically says that dogs who lunge, pull and jerk on leads tend to have neck anomalies, and that the harder and longer they do this the more likely they are to have cervical anomalies.
However this is much the same if the dog itself is doing the lunging, jerking or pulling, as is often the case, including if tethered, or particularly if a dog suddenly takes off and abruptly reached the end of a long line or extending lead. With some dogs even walking on lead can result in sudden thrashing about and lunging and unavoidable targets within their critical distance.
The report does not separate dogs who do this themselves from instances of the handler deliberating checking the dog.
Nor does it specific the nature of the anomalies, and history of knocks and tumbles in play or work etc, nor produce any comparative figures for the incidence of neck anomalies in dogs without any history of pulling.
I have anomalies in my own cervical vertebrate but I have no history of pulling on a lead, with or without a check chain.
Accordingly I am not sure it tells us much?
in terms of whiplash, I recently saw a dog equipment site that stated they wouldn't provide bungey cord leashes due to whip lash injuries from these, i.e. in their experience it was the elasticity that could cause, rather than prevent, whip lash injuries.
