It depends. A few light hairlines is okay. A lot of heavy hairlines is probably not. Without seeing the exact coin with the exact hairlines, that's about as clear as it gets. I saw the other coin you posted and thought it was fine, but without the coin in-hand, I couldn't really disagree with other opinions either. Just looking at a single picture on the internet, there is bound to be some guessing and assumptions about what is there.
