Assuming it's like my dolly, you can do a foot or so without a problem (it's not recommended, of course, but I've never had a problem). I use this trick when I'm leveling the camper with the toad still attached. Also, I will back up a couple inches after loading the car at home - I put a wheel chock down in front of the camper before I load the car (my driveway slopes, so I figure a little extra insurance can't hurt), then I have to back up a bit to get off it before I can go anywhere.
In general, it's okay as long as it stays perfectly straight, but of course what inevitably happens is that it starts to go one direction, and then the entire rig wants to "accordion" together (for lack of a better word) - the rear of the car wants to go one way, the dolly will try to go the other, then the hitch will try to go the same way as the back of the car. Not good.
I got into a situation one time where it was either back up or unload...*sigh* Believe me, I won't make that mistake again...it was a dumb mistake that got me in that situation, and I backed up as slowly as possible so I would go only as far as I needed to.
In any case, aside from not getting into that situation in the first place, be sure to check your straps if you do have to do something like that. Mine loosened a bit when I had to back up. I'm not sure if that's because they'd never been "stretched" otherwise on that trip, or if it had something to do with the backing up.
