It would most likely work fine if done backwards. It would just be less safe, depending on the way things are wired in the laptop power supply unit. If both current carrying conductors (the hot wire and neutral wire) are not connected to any chassis metal, you should be safe (as long as you don't get it wet). Still, it's best to make sure the plug is wired correct, AND the outlet is wired correct. The suggested tester would check for most wiring errors.
North American power also has 240 volts available, with 2 hot wires, 120 volts each to ground. These are not too common and typically wired for dedicated uses such as a heavy duty air conditioner or microwave oven. The power blades on these outlets are different to prevent mixing.
In rare circumstances, you might run into an outlet with both wires hot,
60 volts each to ground. Typically this will be in installations with special sensitivity to noise on the ground wire, such as a sound studio or broadcast station. Such outlets should be marked "Warning - technical power". These outlets will have the same blades as normal 120 volt outlets.
