I have one on 23andme, I share 17cm on the X with her (only segment we match on).

On Gedmatch you can specifically look for matches on your X-chromosome.

Thank you so much for sharing these charts. I'm finding them very helpful! But just to be clear that I understand this correctly ... According to that chart, a woman can not have an X-"cousin" match with someone from her paternal grandfather's family tree. Is this correct?

That is correct. Your father get his X chromosome from his mother, not his father, so you only inherit the X from your paternal grandmother - unless they or your parents were related, which is not uncommon - we all have single ancestors on multiple lineages.
