Yes. A static ARP on the router would work. You could even have the
router do proxy ARP for you.

Example (Cisco router):

arp 10.40.96.2 00a0.8e31.980e ARPA alias

The "alias" keyword means that the router will not only stick the
entry in its own ARP cache but it will also respond to ARP queries
for it, thus advertising the entry to the rest of the LAN segment.
(Which is one flavor of proxy ARP).
