A bored horse may just try to relieve their tension by kicking back at the walls. If they break through, you could have a badly cut leg, broken leg, displaced hip, torn ligaments and a huge vet bill whether it lives of not.
Oak tongue and groove works best if concrete block is out of the question. They may also acquire a taste for the plywood and paint and chew through your walls. Be careful to watch the nails or screws you used, too. Once they get exposed by some mechanism (kicking, chewing, rubbibg or biting) they may get cuts, broken teeth, torn tails or missing eyes. I've seen much of this first hand in local barns.
You can stick with your walls as long as it gets watched regularly. Be prepared to replace sections asap. There are 'no-chew' paints and coatings that can be bought for stalls as well as fences. Keeping some play toys in the stalls can sometimes work to relieve boredom. Having their 'buddy' in there within eyesight helps, too.
Mine are heavy duty concrete block. After one kick, they change their mind...
BTW: if you have extra dead tree branches to deal with, I use my wood chipper to make great stall chips. Easy to sift, absorbent and almost no cost. Pine trees (needles and all( produce a great stall material and make the barn smell wonderful. My Tomahawk chipper has a couple of different screens that can be changed out to select the best one for horse bedding.
Keep this advice in mind once given to me by a famous professional horseman: "Keeping the horses out of the barn keeps the Vet out of the barn".
