You sure there was no *separate* thing to check to ->enable<- "legacy boot"?

I think the problem here was that the kernel in CentOS 6 is too old to boot on a modern laptop, there is not enough back-ported hardware enablement to drive systems that didn't exist when 2.6.32 was released 5 years ago in 2009.  CentOS 7 booted just fine on those devices and should work with SecureBoot enabled as well.
