Yes, on the face of it, the plan is workable. Heat radiation scales linearly with area and exponentially (IIRC) with temperature.

It really is as simple as just adding kilometers of radiatiors. That is, if you ignore the incredible cost of transporting all that mass to orbit and assembly in space. Because there is quite simply no way to fold up kilometer-scale thermal arrays and launch in a single vehicle. There will be assembly required in space.

All in all, if you ignore all practical reality, yes, you can put a datacenter in space!

Once you engage a single brain cell, it becomes obvious that it is actually so impractical as to be literally impossible.
