Yes. That's why he was arrested. However, the seal has nothing to do with it. Breaking the seal isn't a sign of breaking the index, just as breaking the index doesn't always require breaking the rules (see Alice). The index and the seal were made by different people; they just have an overlap in their function.

For starters, the seal is only placed on Artificial Fluctlights, so Kirito never had a seal in the first place. Secondly, it only activates if the person is breaking a rule that was made by an authoritative figure. Most humans in Underworld regard the Axiom Church as an authority, so they regard the church's rules as absolute. However, Kirito does not see the church as such, so even if he did have a seal, it wouldn't have activated.
