Only by editing the filtering code. See kupucontentfilters.js, right at the 
bottom where there is code for copying nodeTypes 1, 3, and 4. Comments are 
nodeType 8, so you could try adding something to copy those nodes. Untested 
code, insert:

else if (kid.nodeType == 8) {
  parentnode.appendChild(ownerdoc.createComment(kid.nodeValue));
}

Be aware that recent versions of kupu in Plone will refuse to edit any 
field which starts with an HTML comment: this allows you to suppress kupu 
permanently for individual field instances.
