The Walking Dead [TV] (May Contain Discussion of Aired Episodes, Enter at Own Risk)

Actually, I would say that makes him safe. In the previous three season finales, they have never had a killed character (in that season's finale) on Talking Dead. Everyone remained alive for the next season.

Now, that's doesn't mean he couldn't be killed, but him being a guest on the season finale Talking Dead doesn't mean his is dead since that has never happened the first three seasons of Talking Dead

Season 2 - Andrea
Season 3 - Daryl and Tyreese
Season 4 - Rick

Plus, ever since Andrea was killed (who had already been pre-announced as a guest on that night's Talking Dead), to avoid potentially spoiling deaths in the episodes, they have tried to move away from that. While it has occasionally happened since, the biggest case against Daryl dying would be Beth. They intentionally kept Beth's appearance on the show a secret (saying "a surprise guest actor from the show") on the episode she died. I can't possibly see them spoiling probably the biggest and likely most controversial death in the series by announcing Daryl as a guest ahead of time.
