No, it’s older.
If it was 2012 or newer then you could use this wiki to dynamically support both bios and uefi systems: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Using_Windows_Server_2012_.28R1_and_later.29_DHCP_Policy
That way you would not be locked into booting one specific hardware style.
Another option would be to install dnsmasq on your fog server to supply only the dynamic pxe boot information for network booting. The reset of the dhcp options (like client IP address) would continue to come from your existing dhcp server.
