AFAIK, no. But check on a CC list.

I've noticed that a lot of people make the mistake of thinking that the
various example licenses published by CC are related or compatible with
each other. They are not. They are intentionally different from each
other - that is why there is more than one of them. Some are closer to a
GPL way of thinking, some are closer to an old BSD way of thinking,
others are completely different again. Just because they are published
by the same people does not mean they are the same thing.
