I'm not sure I understand, but if you mean "Can the phrase 'n-word' be used to mean something other than a particular racial epithet?" the answer is yes, as long as you have defined the conditions sufficiently.
If you said "My daughter just said the n-word!" I would assume you meant that racially charged word. But if we had been having a conversation about how your daughter always says "NO!" and you have started calling it "the 'n-word'" to avoid saying it in front of her, and then said "Listen! She just said the n-word again!" I would know what you mean.
For some people, the "c-word" is "commitment" (as in a relationship) but for others, it's an entirely diferent, very nasty word. I would have to hear the context to know which one you mean.
