Probably less risk in neutral than at higher speeds. As far as I know the decompression levers keep the exhaust valve open for easier rotation of the engine for hand starting. When the engine is running those valves open and close each time a given cylinder fires. These 2 actions are at odds with each other and ultimately something will break.
