Thanks for the reply Sean, yes I did mean square where the image reaches the edges of the circle. I don't know why there would be more noise thought, it's only a small extension of the existing sensor size.

Sorry, I'm still not 100% sure of your meaning.   Do you mean:

a) The lens's image circle reaches the corners of the sensor, or

b) The sensor captures the entire image circle

The "more noise" comment applies to (a), because if you're taking an image that will be displayed in a non-square aspect ratio (as by far the majority are), the part of the sensor that captures the usable width of the image (within the lens's image circle) won't be as wide as a rectangular sensor - so as far as the captured portion of the image is concerned you're dealing with a smaller sensor.
