Practically No, the stack-up of metal layers often hides the gate structures underneath, and the billions of process cells may not all be the same.
Theoretically Yes, as an ion-beam-mill and electron-microscope combination machine can slice up semiconductors layer-by-layer. Given these machines can often also give precise x-ray analysis material data, the exact makeup of the chip can be extracted by competitors given enough time. =3
