That is totally possible and has been done before.
But, you've missed a few things in between.
1. The receiver expects an encoded signal and not a WiFi signal.
2. The receiver binds only to a system that it recognizes.
Here are some suggestions:
1] Laptop program -> wifi + booster -> arduino + wifi -> servo/ ESC
2] Laptop program -> arduino -> RC Transmitter-> RC receiver -> servo/ ESC
3] Laptop program -> internet -> raspberry-pi + data card -> servo/ ESC
Now, wouldn't that be just awesome!
