To apply temporal noise reduction, you must either apply it to the multi-cam timeline directly to the camera angle that needs it, or flatten the clip out. Spatial Noise Reduction works. All if this also applies to using adjustment clips.
Interestingly, TNR also does not work in Timeline mode, but SNR does. I sometimes do this just to see a quick preview of what NR will be like in the final deliverable. Bear in mind that TNR has to see a few frames before and after each clip transition, so it's very processor-intensive.
I don't know if it says in the manual not to use NR on Multicam clips, but it's a good warning. Basically, I tell people, "throw a temp correction on it, live with the noise, do your edit, and once it's locked, flatten the file and THEN do the final color and NR."
