Not sure 'bout the Accord, but I do know that Honda used to support flat towing (using the emergency procedure as you mentioned) their Odyssey minivans. Then, they suddenly stopped supporting this, said not to flat tow them at all. Still, there were several people that reported successfully flat towing them, provided they followed the emergency procedures for such to a 'T'.
Not sure of specific year models for which this would work, nor if it applies with the Accord or not. Me thinks your best best would be to use a dolly or flatbed.
One other 'interesting' option I know some people have done successfully, that you might consider: Just let the Accord's engine run, idling, tranny in neutral, when flat towing it. This comes with its own set of risks, obviously, but is one simple, inexpensive way to allow almost any auto tranny FWD vehicle to be flat towed.
