I haven't tried, but I severely doubt it.
If what you are trying to do is get the lettuce out of the ground, but not
for immediate use, like for instance pulling it at the allotment and taking
it home for later, what we do is pull it complete with roots, and put it in
a bowl of water in the shed till it's needed. Even so, I wouldn't care to
swear that it keeps growing, but at least it doesn't wilt.
I don't know about lettuce, but... a while back I got a container of
alfalfa sprouts, which I kept in the fridge. I put about 1/4th of the
container on a sandwich. Next day the container was full again.
Another 1/4th of it went on a sandwich. And it was full again the next
day! This continued for several days. In all I got about 3 times the
amount of sprouts I'd paid for. Likely there were just a lot of
barely-sprouted seeds in the batch and those were what was growing,
but it sure was funny.
