Is it because the big boys have their bikes already shaved down to the 15 lbs minimum?
Maybe they don't trust carbon the crank arm's strength or rigidity?

CSC uses FSA carbon cranks. I think Cofidis and Davitamon-Lotto do as well. I have not heard of carbon crank strength problems, but perhaps that would be a good reason.

Long driving specialists in golf used to snap the ****e out of carbon golf shafts up until about 5 years ago. Those guys generate 150 mph clubhead speed, the average PGA pro averages about 110-115 mph!

The reason Disco doesn't use carbon cranks, as stated, is that they're sponsored by Shimano, who does not currently have a carbon road crankset.
Many other teams, however, do use them. CSC, damn near all the Campy teams, etc.

Boardman's 'athlete's hour' = 400w
Sosenka's 'athete's hour' = 430w
Boardman's 'best performance' hour = 445w
Indurain's 'best performance' hour = 477w
Rominger's 'best performance' hour = 468w
Merckx = 485w
Moser = 446w

Without looking too hard into it, it seems as though the Shimano teams use Dura-Ace, and most others use carbon

weight weenies says:
carbon: FSA K-Force 53/39 175mm with BB: 790g
aluminum: Shimano FC-7800 53/39 175mm with BB: 779g
same with stems - there's lots of carbon stems on the market. many weigh more than a thomson x2 in the same length. for every super light carbon stem there's a correspondingly light alloy stem (syntace comes to mind).

You really can't draw too many conclusions about equipment/materials superiority by what the pro's use. They're paid to use certain products. That's the deciding factor about what goes on their bikes.

Give that man a cigar.
The OPs original question is just about like asking, "Why doesn't Discovery ride on Colnagos?" The answer should be pretty self-explanatory: it's because they are sponsored by a certain company, and they ride what they are paid to ride.

Boonen doesn't use carbon because Campy doesn't make cranks longer than 175 in carbon. Boonen uses 177.5 cranks and they are only offered in the Aluminum. Otherwise, I'm sure he'd use the carbon version

Many pros aren't near the limit. Cyclingnews.com reviews pro bikes all of the time and many don't drop below 16 lbs. One guy that rides for Bianchi has a 17.3 lb bike.

2. TDF bike weights are anywhere from 14.9-19 lbs.

i don't think pros really care about weight all that much. stiffness yes, weight, unless it's a pure climbing stage, not so much. most of the super ultralight stuff is made to be marketed to weight weenies willing to pay hundreds for a few less grams, not professional cyclists. it's true.

Wow. Dura-Ace products are impressive as far as weight! How can aluminum be lighter than carbon?
