I'm assuming that starting the older diesel engines on gas was to pre-heat them? No glow plugs or other cylinder head heating on those types?
The mechanical injection systems are probably more tolerant of gas or other non-diesel fuel, but I think that will depend heavily on the type of pump. I know the Bosch pumps used on the older mechanically injected VW TDIs (not in any tractor that I know of, but wouldn't be surprised to see other flavors of Bosch pumps or their patents used in tractors) tend to have very tight tolerance, and even short operation with watery biodiesel or gas could cause pump failure from lack of lubrication.
Aside from pump and injector tolerances for modern emissions, a diesel engine will run on just about anything that will burn. Rudolph Diesel originally built his engines to use soybean and peanut oil.
