just before the word internet was used, some people used the terms catenet (for a concatenation of networks) and gateway (for something that did protocol translation) this was around the time of the switchover from NCP to the seperation of TCP and IP - however, the clarity of the simplification you describe about the "architecture" was not, as far as I saw at the time part of the deliberate choice - it is described in dave clarks 1988 sigcomm paper, but that is nearly a decade after that time... the internet you describe is an emergent post hoc rationalisation for IP's alleged parsimony by the way, while ICMP was moved out of IP, the control plane you need to participate in the net (ARP, DHCP, NAT, OSPF, BGP, etc) is by no means simple indeed is mor LOC and bugs than any TCP...
