Yes, you could do that, but also you need to release the old devices in ABM.
Did you yourself or someone in your organization wipe these devices prior to recycling them? If so, you're in no danger of anyone compromising your data. If you didn't wipe them, I suggest sending a wipe command immediately.
More importantly, contact your recycling company and discuss this issue with them. They may not be aboveboard with their practices.
There's really nothing else you can do about them. Wiping a computer doesn't prevent someone from configuring it for their own use later. Locking it will turn it into a brick, which buys you nothing more than satisfaction someone can't use it.

Will not releasing them from ABM cause the device record to generate in Jamf Pro again? I do want to release from ABM but I was thinking to wait for a little while to watch these machines to see if they ever do check in again/get wiped/locked.

Someone else in the organization wiped them a long time ago and did not uncheck them. The only problem is some of our configurations redeployed so licenses of services we use are back on the device for example our security softwares that should no longer be on the device. I will probably keep them and wait for awhile to see if they ever check in so that the wipe command runs. I removed them from pre-stage to stop our policies/configs from redeploying. Would it make sense to remove from ABM now? Or should I wait until we decided they are never going to check in again?
You can send a wipe command to remove your apps and settings, but you'll never really know if it worked except if the computer re-enrolls itself.
Remove them from whatever PreStage enrollment has them scoped, and they can't re-enroll into Jamf Pro. Then send a wipe command. Wait a few minutes for things to go through and then you can delete them from Apple Business Manager.
I think that should take care of it.
Enable authentication in your PreStage. It won't resolve the issue if your devices not being unassigned/released as part of your e-waste process, but it will stop random devices being enrolled.
You also need to look at your ABM unassign/release practices and the agreements in place with your e-waste provider.
