I'm considering mounting a beam for climbing exercise equipment similar to what is pictured below (see here for complete details):
The set up (in my case) would consist of two 20" 2×8 base boards each mounted ~40" from the corner attached to two studs each via 5/16" lag screws. Between the base boards would run an additional 56x2x8 main beam mounted to the base boards via angled joist hangers. However, in my case, one of the base boards would need to fixed to the wall above a window.
My question is: Would it be a horrible idea to mount a base board above a window?

No, there's no problem doing so. In fact, you probably have the best substructure there. You'll find a 2x6 or larger header either directly above the window or below the top wall plate. You should also find "cripple" or "pin" studs on standard centers over or under the header.
Be aware that some header designs leave a 1/2" or larger insulated gap between the framing and the drywall if the load-bearing members are sandwiched together and installed at the outside of the wall thickness. You could potentially cause significant drywall damage by pulling your lumber tight with bolts. Press firmly on the drywall where you plan on bolting to feel for flex, then proceed slowly when tightening, keeping an eye out for movement.
