Are my Shimano RS80 C24 wheels tubeless compatible?

I have a set of these wheels on various road bikes since 2011 maybe earlier. When I bought them I believe I was told they were tubeless compatible. I was about to finally convert them this weekend when I started to worry I had imagined it.
I have searched extensively online including the manuals on the Shimano site and there is no mention.

I would prefer not to bother if they are not specifically designed for tubeless as there probably isn't a huge amount of life left in them? I can't tell by looking, does anyone know for sure?

I'd be very surprised. I have a couple of sets (or did - a friend had the Cayo that had one set stolen) and there's noting about them that makes me think that they are. Besides that, I'm not sure I'd bother.
