Can my son get a new 45-day entry stamp by flying to Laos from Thailand?

IF you are looking for a "service provider" to go to the border with post in a group related to where you live in Thailand. You'll get recommendations

If their stamp runs out Oct 29th that's the day they need to stamp out by. Staying AFTER that stamp runs out gets an overstay fine of 500 baht a day.

I didn't see you had a pending post, and I posted this already

There's no need to fly to Lao or anywhere to get off the 90 day STV entry stamp and get a new 45 day visa exempt entry (it's NOT a visa it's just a free entry stamp), You can do it by land OR air and there's no amount of time you have to be out of the country.

There's no need to fly to Lao (where most people need to BUY a visa to get in when they land) you can fly to Malaysia, Singapore, anywhere you can get in and out of without a visa. Check flights, he could fly out one morning and fly right back in that afternoon.

IF you wanna go to Lao then Vientiane is where you fly in to. They won't have any issue comin' back in as they don't have an extensive stay history (many covid extensions)
