There is a way to get it to work by plugging in the thunderbolt cable between the two computers, and look under the network settings for the "Thunderbolt Bridge" device. Assign each one a private IP different than each other -- even in the "self-assigned IP" space i.e. 169.254.35.10 and 192.168.35.11 - Click on "Advanced" and make sure one of the interfaces shows "Active" From there on the higher-res display, you can VNC over to the other one: Finder -> Go -> "Connect to Server" and enter: vnc://169.254.35.10 or whatever the IP of the other computer is.
Although this isn't Target Display mode
You're right this isn't TDM. With TDM you would be using the iMac screen as a second display to your MBP. You would be running software on your MBP and use two screens for it (the iMac would act just like a monitor).
With the process you are describing, you'd just be accessing your iMac remotely - i.e. you'd be using a window in your MBP screen to show you the screen of the iMac, and run applications on the iMac.
Two very different things!
And, to be sure, the latter can be done whether or not you use a Thunderbolt cable, and Thunderbolt Bridge. The two macs could be just connected to the same LAN using Wifi, or even just be connected to the internet half the world apart.
And instead of the general vnc:// you could use Apple's implementation of ScreenSharing.
