I'm curious if OpenBSD runs on one of the current Atom tablets that weight

Broadly speaking, no. They generally have either UEFI without CSM or in some cases completely custom boot environments that OpenBSD does not support. The Dell Venue 8 specifically omits the CSM from UEFI.

Increasingly, only servers, corporate desktops, and "enthusiast" motherboards (for DIY system builders) are coming with the UEFI CSM required to boot OpenBSD. Otherwise the inclusion of a CSM seems to be largely relative to how old the BIOS is, and how "corporate" the product is. Note, also, that just because the mfgr includes the EFI CSM, doesn't mean it works correctly :-(. Bug reports that never get addressed are common.

The Lenovo Yoga 2 (10") and/or Lenovo ThinkPad 10 might work; there are many anecdotal reports of legacy booting on the both not working properly *until* the internal disk is correctly formatted with an MBR and boot sector... catch-22!
