It could. DHCP servers are allowed to use more than one parameter, such as mac, hostname, etc. It could cause trouble with many dhcp servers though.
I'm using the DHCP server in my pfSense firewall. The only identifier is the MAC address.
I'm not sure what DHCP implementation that uses; it might be something less featureful than ISC DHCPD, maybe? Or perhaps the configuration tool doesn't manage everything supported in RFC 2132? When I tossed my Pine64 single board machine onto my LAN, when it negotiated with ISC DHCPD, I could see in my logs that it reported in as being "pine64". Presumably that's part of one of the further extensions (e.g. - transmitting more than merely the MAC address). -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"
