Yes, a leaf or two is safe, though most cats ignore it.

Why it’s fine

Lettuce is mostly water and non-toxic, with a little fiber some cats enjoy chewing — often to help fur pass through the gut. It is nutritionally nearly empty, so there is nothing to gain, but also nothing to fear from a clean, plain leaf.

How to serve it safely

Offer a small washed piece of plain lettuce; shred it if your cat prefers nibbling bite-size bits.

When to call the vet

Call your vet only if repeated vomiting follows a new food.
