It doesn't. You can breed any couple of Lichen + Crystal from level 4 or greater.

It's just said that level 15 or greater dragons have improved chances to get rare dragons - but they don't say how much improved.

Last month I've got 3 Diamonds with level 10 couples. This month I'm still on the first Emerald with level 15 couples.

I don't see much difference with a leveled dragon. But leveling your Island and Cave improves your chances a lot, since you get more attempts.
