Having had the 80-200 AF-D model myself, I wouldn't want any of my cameras (no matter what camera and what material it was made of) with that lens hanging off the mount freely like that.
I would (almost)always be sure that the lens is carrying the camera .. not the other way around.
Although in saying that, I have mounted that camera lens combo via the camera(on a tripod) on a few occasions, but only for a short time(a few minutes tops) and always tried to be extra careful too. Mainly for testing various stuff, not for everyday situations.
If you have the push-pull type lens .. sorry can't offer any advice or experience on the topic of your issue.
(except that theory would dictate that you could do so, up to the point where the situation failed you in some way. The problem is trying to predict this point of failure)
