Certainly. The 10/Swords is often about (1) all that needed to be said has been said, meaning no more need be said; everyone is completely informed. And/or (2) those who are wise already know all this and need not be told, and those who are not wise should not be told. So, silence is golden?
Addendum: I've said this before, and I hope my Moon Gemini doesn't get a "here she goes again..."
but RWS 10/Swords image reflects the tale of Solomon's architect who was murdered because he wouldn't give out secrets to unworthy men. Given that story, the 10/Sword's Sun-in-Gemini could indicate the highest logic and wisdom and reason behind the talking. Meaning that it can see, by the light of the sun, who is worthy of hearing these words and who is not. And not even the threat of death will make this person give them to the latter.
The murdered man, thus, is a martyr and example to those who would learn the highest secrets. If you get this card, then you are wise enough and mentally courageous enough to have been told such information. You are willing to die rather than give this information to anyone who isn't worthy.
