Supposedly yes. Following these instructions, I was able to get the 7290 to respond to AT commands like a normal modem. But when I tried to dial (ATDT) I got an error back. Maybe you'll have better luck.
HOWTO: BlackBerry As Modem For Laptop
SUCCESSFUL CARRIERS: AT&T, Vodafone, Rogers, CINGULAR!
SUCCESSFUL MODELS: 7100 and 7290
SOMETIMES SUCCESSFUL: T-Mobile (port blocking issues)
UNTESTED: Nextel 7520 (need to dial S=2 instead of *99#)
Did you know that BlackBerry can now be used just like an external modem for a laptop computer, so that a laptop can have full Internet access? This is useful when you need to do certain things that a BlackBerry cannot yet do. Increasing numbers of success reports have caused me to post this message. (Note: Mark Rejhon has not himself yet successfully used a BlackBerry as a modem; I am aggregating information). Sometimes, it is still tricky to set up a BlackBerry as a modem for a laptop, but this feature is becoming more and more common in cellphones, and BlackBerry models are following suit.

3. Supported BlackBerry Models
You must have a BlackBerry model 7100 or a model 7290, or a Nextel 7520. At this time, no successes are yet possible on older BlackBerry models, and may not ever be. This may change with a release of BlackBerryOS 4.0, but there are no guarantees.
4. Supported Carriers
Currently, T-Mobile, Rogers, AT&T, and Vodafone UK are reported to work. No confirmations for other carriers yet.
5. Connect Your BlackBerry
Make sure your BlackBerry is connected by USB cable, and your BlackBerry Handheld Manager is running (just launch BlackBerry Desktop to run it.) This is necessary for using the BlackBerry as an external modem. You cannot use BlackBerry as a modem unless you have BlackBerry Handheld Manager running in the background!
6. Modem Driver Install
If you installed a recent version of BlackBerry Desktop that came with a 7100t or 7290, it should include modem drivers and already be automatically installed. In the event you need to manually install them, the modem drivers should be located in this directory:
C:\program files\Common Files\Research In Motion\Modem Drivers
7. Verify The Modem Driver Is Functioning
Go to Control Panel -> Phone & Modem Options. In the Modems tab, you should see a new Standard Modem on a new port (such as COM6 or COM11). Click Properties -> Diagnostics -> Query Modem. You should see the following:
ATQ0V1E0 - OK
AT+GMM - BlackBerry IPmodem
AT+FCLASS=? - OK
AT#CLS=? - OK
AT+GCI? - OK
AT+GCI=? - OK
ATI1 - Research In Motion / BlackBerry IPmodem
ATI2 - Research In Motion / BlackBerry IPmodem
ATI3 - Research In Motion / BlackBerry IPmodem
ATI4 - Research In Motion / BlackBerry IPmodem
ATI5 - Research In Motion / BlackBerry IPmodem
ATI6 - Research In Motion / BlackBerry IPmodem
ATI7 - Research In Motion / BlackBerry IPmodem
8. IMPORTANT SPECIAL CONFIGURATION STEP
