Seems so:
ctvdr:~# cat /sys/class/dmi/id/bios_vendor
coreboot

Let's take a different example:
erwin:~# dmidecode -t bios | grep Vendor
        Vendor: Award Software International, Inc.
erwin:~# cat /sys/class/dmi/id/bios_vendor
Award Software International, Inc.

If you want to be sure, verify with the dmidecode source code.

BTW: I found a shorter dmidecode command line:
ctvdr:~# dmidecode -s bios-vendor
coreboot
