its risky but before you use them just rehydrate first. If they don't ferment youll have to add another yeast within 48 hrs. Keeping them frozen wont make any difference at all

I'd also add the lower the OG of the beer you plan to put it in the lower the risk if a stuck fermentation
The viability of the yeast will depend on how well it's been stored. Keep it in the fridge. If you rehydrate the yeast before pitching this should give you an idea of how healthy it is. I wouldn't pitch it in the beer without checking it out like this first.
I would say be careful....I havnt made alcohol with out of date yeast but I have made bread with out of date yeast and it just didnt rise.
as suggested above, make a yeast culture to see if it is live.... warm water (200ml-ish) 1 tablespoon sugar, yeast.... leave it in a warm place for a day or so, if it froths up and looks active, great; if not, its dead and youll need to replace. :)
