If I plant lettuce seed rows not all at the same time, can they then be planted closer together?

I think you are trying to do succession planting? Every week or so a new row will be read to eat?

Seedlings still need light so crowding wouldn't be a good idea. At least that's my thoughts on it..

Lori is right. Also, remember, you only see the top half of the plant. The working part is the root system buried underground. If you have seedlings battling established plants for root space the seedlings will loose every time.
