You can, but most open-source license make little sense when applied to binaries. Like in this case, the Apache 2 license doesn't make distinction between the source and binary, referring to both as "the Work":

> You may reproduce and distribute copies of the Work or Derivative Works thereof in any medium, with or without modifications, and in Source or Object form, provided that (...)

Applying this only to their binaries directly contradicts what the license says.
