Not necessarily.
From TNG “The Neutral Zone:”
DATA: Since we have had no contact with the Romulans for fifty three years, seven months, eighteen days, we must consider that the information we do have, is out of date.
This changes after YE. Picard is aware of the Romulan attack on Narendra III in 2344 and knows that the Enterprise-C was destroyed by Romulans, because he states this to Guinan in “Redemption:”
GUINAN: How much do you know about what happened to the last ship called Enterprise?
PICARD: Enterprise C? She was lost at the battle of Narendra Three, defending a Klingon outpost from the Romulans.
So something changed.
