Succinctly, yes, although that provision is a big one.
I'm running Bro on two 10 gig interfaces, an Intel X520 and an Endace DAG 9.2X2. Both perform reasonably well. Although my hardware is somewhat underspecced (Dell R710s of differing vintages), I still get tons of useful data.
If your next question would be "how should I spec my hardware", that's quite difficult to answer because it depends on a lot. Get the hottest CPUs you can afford, with as many cores. If you're actually sustaining 10+Gb you'll probably want at least 20-30 cores. I'm sustaining 4.5Gb or so on 8 3.7Ghz cores, but Bro reports 10% or so loss. Note that some hardware configurations will limit the number of streams you can feed to Bro, eg my DAG can only produce 16 streams so even if I had it in a 24 core box, I'd only be making use of 2/3 of my CPU.
