Wirelessly? Sorry but no.
The Bose speaker is set up to play music from iPods and iPhones using Apple's Airplay Wi-Fi streaming facility. It won't connect to a Sonos network and appear on your Sonos Controller app, if that's what you're asking. I had a quick look at the manual and it doesn't even seem to support playing music files from a PC or NAS drive over a Wi-Fi network either.
The Soundlink does have an AUX input. If you have a Sonos Connect you could connect a cable from audio out on that to the AUX in on the soundlink and use the Bose as a speaker.
