Well yes of course. I'm envisioning a park with natural and human-made barriers to keep them in their area. We already manage large predators in the lower 48 states of the US by tracking and monitoring wolves and grizzlies. If it's a choice between polar bears going extinct at the North Pole and surviving comfortably at the South Pole, I'd choose the latter.
