Absolutely. But it was a pretty common tactic during the Cold War to claim (falsely, or semi-falsely) that, say, the Russians didn't have a word for "freedom" or "privacy" or "compromise" as proof that they were the Borg.

As if we English speakers don't get ohrwurmer just because we don't have a nice neat word for it.

Pratchett much more sensibly points out that a lack of a word doesn't necessarily mean a lack of a quality - just a lack of alternatives to that quality necessitating a label to differentiate it.
