Sadly no. The hazard is caused by the pull-down socket design - sockets don't hold the bulbs snugly and this can cause a fire risk. It's the ballast that overheats when the bulb connection isn't made properly, and can catch fire.
So a LED bulb would fall out just as easily as the others, and bad connection make the ballast overwork etc.
Otherwise, I would buy the LED bulb and put it in the same fixtures.
