Yes, it can be done.

Note that arctan(1)-arctan(0) is being recognized as the desired symbolic solution (pi^2/4).

Just kidding. The hard part is to get there through some clever symmetrical substitution like u=pi-x, and some other substitutions, a shown here

Not sure if that recognition pattern has been implemented in Giac/Xcas (maybe it is too expensive).
