Yes.
Please see the newly-updated wiki page regarding this (at
http://wiki.wireshark.org/CaptureSetup/Bluetooth). It's been a long time since I've worked with Bluetooth, but I clearly remember it working under Fedora without any additional configuration, or effort on my part.
A "hcidump" utility from the developers of the Linux Bluetooth stack/BlueZ also exists, should you prefer to use it to generate (Wireshark-compatible) logs, instead - although it doesn't quite meet the criteria of "live capturing and display" (since you have to manually reload its generated log in Wireshark).
You could also try running "tshark -D | grep bluetooth*" (or "tshark -D | grep hci*") as root, or using "sudo" to see if your Bluetooth interface appears.
I hope that helps,
