Is EBS not, itself, a SAN?
To me, a "Storage Area Network" is 1. a cluster of disk-servers, serving the role of exposing logical block-storage over a protocol like iSCSI (whether directly to client machines, or managed and dynamically allocated by hypervisor software like vSphere), where 2. machines are connected to that storage cluster over a dedicated network interface, to keep LAN/WAN packets from contending for throughput with SAN packets.
By that definition, EBS is definitely a SAN. (And technically, so is my two-drive NAS, if I configure it as an iSCSI target and then run a second switch that connects to its second network port and my workstation's second network port.)
Does "SAN" imply some specific internal architecture for the storage cluster or something?
And, if so, then what do you call the type of thing that EBS is?
It implies purchasing dedicated hardware. SANs are CAPEX heavy solutions.

If you insist, you could call EBS a SAN-as-a-Service, I suppose.
