No, Rachel's scars were removed in Excalibur 52
The Phoenix Force restored Rachel in Excalibur 52 and removed all of her Hound genetic modifications, including the Houndmarks.
Whatever happened in Kingbreaker #4 undid everything the Phoenix Force did to Rachel, including removing the Houndmarks.
Seems like a stupid retcon to me, but oh well... And why Rachel can't cover them up like she used to has not been explained.
