Those don't look like squircles to me. If they are squircles, they're so close to simple rounded rectangles that there's no meaningful difference left.
The keys could, maybe, be squircles, but I'm having a very hard time seeing the outline, the touchpad, the outline of the keyboard as anything other than rounded rectangles.
