I have an old butcher block table, mounted on steel legs, that is cupped on one side. Is there any way to flatten it without removing stock?

You may have to delve into the wonderful world of steel on this one. A couple of lengths of 2' x 2" angle with elongated holes underneath should do the trick.
Are you saying I take these steel angles and just screw them into the bottom?
Yes, indeed. If the profile cannot be gracefully hidden underneath, you may wish to cut a slot so that the vertical tang can slide up into the wood, depending of course on how thick the top is. The unit already has steel legs, so you're consistent in the materials. A warping butcher block top will overpower all but a disproportionately large wooden rail. The steel angle is relatively cheap, easy and permanent.
To give any kind of a useful answer a lot more detail is needed. Dimensions?, is this a true butcher block with an end grain surface?, cupped on one side means what? and how much is it cupped?, how are the legs mounted?, is there a frame or apron under the table?

John,
Dimensions: 24x36x1.75
There is a bottom shelf attaching the legs.
There is no frame or apron, just a top attached to legs.
The cupping is "S" shaped on one side with a slight lower edge sag on the other. The deviation is about 1/4". The original purpose of this table was for trendy kitchen use.
It may be possible to pull that thick of a top flatter by very solidly screwing it to a very stiff frame underneath, but it won't remove all of the warpage and the stress could crack the top. Also, you will have to attach the framing to allow for expansion and contraction to prevent cracking if the top shrinks.
In the long run it will be easier to plane it flat, but the top may still warp with seasonal moisture changes. Usually butcher block tops are glued up from narrow boards which discourages warping.
Another possibility is that the top has a much heavier finish on one face than the other which would cause warpage because of uneven moisture absorption. If that is the case, evening out the finish would reduce the amount of warpage.
