Yes it can. But leave this work to a qualified electrician. The consequences of doing this improperly range from failure of the cooktop to work, to damage to the cooktop, to an electrical fire, to injury or death due to electrocution. The hazards cannot be stated strongly enough.
This could occur if the 120V supply is split-phase, where two 120V lines are 180 degrees out of phase with each other. When measuring from one of these lines to the other, you would see 240V. This is a common setup in residential electrical systems in the United States.
120v and 240v cords usually have different end configurations and will not plug into the different recepticles. However, if you changed the plug end, and the cord has the proper size rating, then yes, you could use the same cord. But, it also depends on the cord too. Most 120v cords only have three wires in them. One "hot one "neutral" and one "ground" wire. A 240v cord would have FOUR wires, two "hot" wires, one neutral wire, and one ground wire. Therefore, if you changed the voltage from 120v to 240 using a 3 wire cord, you'd not have a ground wire and that could be VERY dangerous. Note that occasionally a 240v device (e.g. some motors) will only need three wires (red,black,green, no neutral) and can be wired with a 120v cord if the cord is rated for 240v.
There are no adptors to plug a 240v plug into a 120v receptacle. 240v requires two hot wores and a neutral and ground. 120v requires one hot wire, a neutral and a ground. If you have something that runs on 240/120 you need the cord and adaptor that came with the equipment as you willl need the wires to mate up accordingly.
No, SJ type wire is not rated for 277V application. This wire is typically designed for lower voltage applications such as 120V or 240V. It is important to use wire with the appropriate voltage rating to ensure safety and compliance with electrical codes and standards.
4 wire household wiring is black, red, (hot wires) white (neutral) and bare or green (ground wire). You say 3 wires. Is it 120v or 240v. If its 240v which is more common just use the two hots and the ground and cap off the neutral wire.
Don't!
Theoretically that can be done with transformers, but the power available would still be limited by the circuit breaker on the original 120 v supply.
With one interpretation of this question, the answer would be two 120V wires and a ground.
Short answer: probably not. Longer answer: It depends on the size of wire feeding the stove, the stove amperage, and what you intend to connect to the new 15A circuit. If you just want to wire a light for the garage, sure go ahead. If you want to install a receptacle for a microwave oven, no way. Make sure you put a fuse to protect the circuit you are connecting.

You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit and put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated.

What specifically are you wiring? A light bulb would operate dim, a motor will burn up. The current increases thereby requiring larger wire and current protection.

The burners will most likely be 240V. By keeping the range at 240 volts it will use less amps that at 120V. Say a range and oven is rated at 9000 watts. Watts = amps x volts. 9000/240V = 37.5 amps. 9000/120V = 75 amps. As you can see at 120 volts the amperage is double over 240 volts. You would need a 100 amp breaker and #4 wire to accomodate the range on 120 volts.
