Can the intranets on both ends of the IPSec tunnel be on the same subnet?

No.

If the two networks are on the same subnet, the local gateway considers a packet destined to the remote network as a packet exchanged within the local network. Therefore, the local gateway does not forward the packet to the remote network through the IPSec tunnel.

NOTE:

If a headquarters establishes IPSec tunnels with multiple branches, the headquarters network and the branch networks cannot be on the same subnet, and the branch networks cannot be on the same subnet, either.

No is the easy answer but sometimes you don't have any other option. If this is the case you can always use some NAT tricks to solve your problem.
