Can I leave Thailand with an overstay and pay a fine at the airport without canceling my business visa?

The user has overstayed their visa by 20 days while holding a work permit with a BOI company. They inquire about the possibility of leaving Thailand, paying a fine at the airport without canceling their business visa, and whether they can return in the future. In response, it is suggested that they can clear the overstay at the airport, and afterward, they should visit the BOI office to cancel their visa and work permit. Alternatively, if they cancel the permit first, they may need to go through additional procedures to leave.
