No. The milkshaking tests measure the total CO2 in the blood, no matter how that TCO2 gets to where it is (lasix shot pre-race, feed, milkshaking, etc)
Any trainer (or vet) that uses Tums or Rolaids (instead of plain Arm & Hammer baking soda) to "milkshake" probably isn't very bright, IMO, as they are, first, wasting a ton of money :D, and secondly, using calcium carbonate inside of sodium bicarbonate. Not the same metabolic effect.
Bicarbonate ion is the conjugate base component of bicarbonate:carbonic-acid buffer, the principal extracellular buffer in the body. Plainly, it buffers acid, hopefully delaying muscle fatigue. Sodium bicarb is a great and quick pH buffer, but the massive amounts of sodium can be problematic.
Calcium carbonate (the weak "oral antacids" like Tums and Rolaids) are not antacids for the pH of the blood or extracellular space, they are intra-GI tract antacids. They target excess hydrogen ions within the GI tract (which doesn't affect the blood or extracellular fluid pH). Calcium carbonate will bind with phosphorous in the gut (preventing absorpsion), and the calcium is poorly absorbed from the gut and so passes out and does essentially nothing to the blood in even massive overdose (luckily, as if it was absorbed en mass, the calcium would probably cause cardiac problems). Possibly cause a constipation colic. If they administer it regularly, could screw up the horses bone density.
The effect on the bodies acid-base buffering capacity ... essentially nil.
They aren't cheaters because they are smart.
