Yes, some non-ionizing radiation can cause health problems. Your question is very broad - you've asked about non-ionizing radiation generally, rather than say specifically about radio waves. And that makes it much easier to answer in the affirmative.

See, for example, photochemical damage of the retina from high-intensity visible light:

Also, high-intensity near-infrared radiation will kill cells.

And focussed microwaves are also non-ionizing and aren't particular kind on fat and proteins either:
