Yes. Those language customisations change the wording of the text that students see, so if you set it to display and the text was empty (e.g. put a there), then the activity name will show up greyed out, but there will be no wording of the actual restriction.
Actually the word "Restricted:" is still there. But you could zero that out too.
But it would happen everywhere. (At least with that language pack.) You'd have to go into the settings to see what the condition actually was if you are a teacher or admin.
