IPTC data are metadata that are added "along" the image and embedded in the file. It shouldn't affect the image part at all...
Just to be quite sure
, I used imagemagick "identify -verbose" to check that the Signature (ie: checksum) of the image was the same before and after IPTC creation/edition (I used all fields). Results => Same-Same... 
So yes: XnView does support lossless editing (just as it should be).

Re: IPTC editing lossless?
The browser's compare tool displays equal crc also (interesting to me because it shows that the image data is being checked (unlike a typical archiver which uses the whole file).
