Yes, but if you are below V1 and the fire bell goes, you're quite simply a dork if you take it airborne. No ifs, buts, whatever. To consciously take a potential fire airborne when you are already on the ground and freely able to stop, even on a limiting contaminated runway, show peculiar judgement. One needs to go into a darkened room and re-examine one's decision making processes. Period. There is no exception.
Next question please!
