As long as both are SX tranceivers, yes.
The tranceivers shouldn't be aware of what the other side is; it's akin to a HP made Copper port talking to a Cisco made Copper port over a piece of Cat 5.
Where you run into issues are where you're trying to use the other vendor's tranciever in your gear.
With fiber you need to make sure that you're matching like trancievers (SX/LX) on each side, as well as using appropriate fiber between (MM/SM), but this link will work fine.
Right now you can't use any of the "Direct attach" CX1 cables between Cisco/HP, which is a pain- because those are so cheap. But the vendors are kind of in a staredown right now, so users are caught in the middle.
