I have an old car phone and wanted to test the function!

The plug has the same shape as my internet cable and would also fit in my laptop!

Should I connect the car phone to my laptop?

What would theoretically happen?

That can end badly. The laptop can be grilled, especially when the car phone also supplies electricity.

the modular connector is very common. It exists in all kinds of devices.
