is it that the larger the image the larger the noisethreshold can be?

not really
the grainer you like the higer you set and vice versa
it depends on whatever you want to do, noise is noise, at watherver resolution and wathever quality, personally i like a bit of it (0,02-0,025) especially on fstorm wich have a good "quasimontecarlo" feeling and not pattern based
but most of the people doesn't so a threshold of 0.015 or less is required if you don't want to be in trouble, i mean...it's basically noiseless provided you set a decent number of samples and guess what that means..
time
even if you render a REALLY high res (which i strongly discourage you to do) and downsample then you are basically gaining nothing..
to test it yourself try make a white cube with a light and render at 8kx8k and you'll see that it'll take a life to render (well minutes really) and keep an eye on the ram manager...that will let you make an 1+1 and understand that it's not going to be a smart thing
so to recap the straight answer is...
could be just because of the loss of information on downscaling can trick you to see it less than the full res. but if you do that to cut the rendertimes it's not an option since to get a decent amount of reduction it will take the same if not a lot more of the time to render so no deal...
