Twice in the time I've been driving, I've had catastrophic coolant losses while moving. The first was a plastic cooling hose junction "blowing up" for lack of a better term on the interstate, while the second a series of events that bent a fan blade that in turn gouged out the radiator at somewhat lower around town speeds.
In both cases, I drove probably more than 30 seconds after noticing the coolant loss to get to a safe stopping place and safely get the car stopped. The gouged radiator was driven ~100 feet off the truck and into my car port as it would have been nearly impossible to get the roll back closer and it needed to go up a hill that needs a half dozen people pushing a car to get it up(don't ask me how I know that...).
The one that went on the interstate was a newish and fairly high strung DOHC aluminum V8(Lincoln LS). It had 110K on it when that happened, and had 156K when I sold it a couple of years later. I last saw it around town a few months ago, and the new owner has put another 20K on it with nothing other than routine maintenance.
The gouged radiator was in my MG, which admittedly is an old sloppy cast iron OHV I-4. Still, though, it continues to run perfectly fine.
I wouldn't think twice about running a stone cold engine without coolant long enough to move it around my driveway. Running it up to temperature wouldn't be a great idea, but it's not going to hurt anything in the amount of time that takes.
