Not exactly. (I see that you said megapixels and not pixels, but this is a point of confusion for many, so I'll go on for the noobs). Big pixels, all other things being equal, give lower noise, but less detail, particularly when cropped. The 7D has a very dense pixel-pitch, which will sacrifice some noise, but yield more detail.
I'm worried about large pixels on the 1D-X. The 5D MkII will likely yield more detail on cropping than the amazing new X, which is stunning in all other regards.
So, for cropping, you want small, dense pixels, shot at relatively low ISOs. For high-ISO with low noise, you want large, efficient pixels.
