Wikipedia is not an authoritative source.
However RFC1122 lists BOOTP, the predecessor of DHCP, among the support 
protocols of the application layer. So be it...

Common mistake. A protocol layer is defined by the service it provides, 
not the protocol layer it is based upon. For example NDP is based on 
ICMPv6 (network layer), itself based on IPv6 (also network layer) but is 
in the link layer.
