The legacy BIOS does not contain support for GPT*, but GPT contains an emulated MBR so that a legacy BIOS should be able to read a GPT disk and possibly even boot from it if you're lucky. :-)
I tried this only just the other week - no luck here. Legacy BIOS with 2 x 3Tb harddrives. I had to let it boot over PXE.
But the problem here is the size of the disk, not that it is GPT. My current desktop machine boots a 2 TB hard disk partitioned as GPT, with BIOS. Not emulated BIOS, but real BIOS, the machine predates UEFI. The disk does have a "bios" partition, unused.

The bios partition (in my case, 7MiB) is only used if the MBR contains grub. In my case, it doesn't: => Syslinux MBR (4.04 and higher) is installed in the MBR of /dev/sda. And YaST in 42.2 or 3 handled the situation nicely. I don't know about 15.0, it is new code. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
