Can I run a 200 amp sub panel?
Yes, and you don’t even need another 200A breaker. The 200A breaker alread present in the panel will suffice, and so you can use a subfeed lug kit as DrSparks advises. For that matter, if the main breaker were out at the meter (e.g. a meter-main), you could simply “tee” off it with dual 4/0 to two main-lug panels.
Why does my house have 2 breaker boxes?
The secondary breaker box is called a sub-panel and serves to split the load for the building to cover multiple areas. It can also be used to isolate one part of the building from another electrically.

Does a sub panel in a detached garage need a main breaker?
The subpanel may be equipped with a main breaker to allow for power interruption without having to go back to the main panel, but it is not required to have a main shutoff circuit breaker, since the feeder breaker back in the main panel serves this function.

Nothing inherently wrong with 2 100A breakers in one box plus lots of other breakers – i.e., oversubscribing the 200A total is perfectly fine if real-world usage will stay under 200A.
Why do I have 2 breaker boxes?
