m9 high iso and print size

It should look fine- if you would print Kodacolor 400 or Tri-X at that size, ISO 2500 should not be a problem.
ISO 2500, Nokton 50/1.1 wide-open on the M9:
100% crop, more like a "Poster size" enlargement. A 72" screen would be required to view the full image at this resolution.

Sure it does...since noise limits detail.

That makes no difference in print size. Images don't change because of size--there is no change in the information that is contained in them. The noise won't increase nor decrease.
A photo from an M9 at ISO 160 will hold up better when printing at larger sizes than at ISO 2500. The noise does not increase in volume (but will in size just as grain does), but the increase in noise at 2500 (as compared to 160) will not hold the same amount of detail as the ISO 160 photo. So there is always a change in the amount of detail and dynamic range the further you go away from the native ISO. Have you printed photos from an M9 at 160 and at 2500 in large sizes (say 13x19 or larger)? I have and the 160 ones hold up a lot better generally speaking.
Also, I would argue that images do change because of size... not the content obviously, but the "defects" within images are amplified more and more as one goes larger and larger.

Sorry, not being clear. Noise is just the result of the process and will be inherent in the image. At a standard viewing distance, it will be just as obvious regardless of print size. I print all kinds of images on 44" large-format printers. Quite a few of my "clients" come in saying a particular image can only be such and such a size because of pixels/noise/the force/etc. I have yet to have anyone leave believing an image is limited to a particular print size.
I can understand that. My line of thinking is that there will be more detail in a ISO 160 print than a ISO 2500 print of the same size...so sticklers for IQ may not like what they see in a large print at ISO 2500. Of course, people have made billboards with older digital cameras with only a few megapixels so it can be done (and done well enough). It just depends on your expectations is what I meant.

I'm really surprised that the large areas of Black in this image do not show pattern noise. The latest versions of Lightroom seem to have greatly improved noise reduction.

100% crop.
Not bad for a 73 year old lens.
