Yes. Take them out of the fridge, in about 3 days when they're warmed up, give each of them a shake to resuspend the yeast, and check on them in another 2-3 weeks.
Remember, The
3 weeks at 70 degrees, that we recommend is the
minimum time it takes for average gravity beers to carbonate and condition. Higher grav beers take longer.
Stouts and porters have taken me between 6 and 8 weeks to carb up..
I have a 1.090 Belgian strong that took three months to carb up.
And just because a beer is carbed doesn't mean it still doesn't taste like a$$ and need more time for the off flavors to condition out.
Everything you need to know about carbing and conditioning, can be found here
Of Patience and Bottle Conditioning. With emphasis on the word,
"patience."
Next time, 2 3 weeks, take 2 bottles, one from each case, or at least no near each other, stick them in the fridge for 48 hours minimum, and try them, if they are carbed and taste the way you like, go ahead and chill some more, if not try one in a week, and keep checking.
But don't chill the majority, til you know they're actually carbed up
