Yeah you would need 10-20 American football fields worth of radiators for a single data-center... so yes, it "can" work, but it's completely inefficient and unrealistic.
The plan is to launch a constellation of smaller AI sats not a monolithic large data center. The calculations I have seen actually have a smaller radiator area than solar panels. Scott Manley’s has a video on this where he goes into some numbers.
