You can and it will probably work for awhile but unless you are extremely observant its going to eventually crack and leak. If the engine overheats it can cost a lot more than what the radiator costs to replace.
Basically max effort and being constantly worried when its gonna fail next. Or just suffer the $150 bucks and 45min job it costs to swap it out and its probably gonna outlast the car.
