Test your app on a 3.1 device (or emulator if you don't have access to a device), but generally, yes. It may be windowed or not show in the market you don't specify proper large screen support in your manifest, though -- read more on the Android developers site: http://developer.android.com/guide/practices/compatibility.html

Android 3.1 is optimized for Tablets, while your application will run it may not function visually the same due to it being massively scaled up for a tablet sized screen. If you are unsure how it will look then set up the emulator included in the SDK and set it to the screen size/resolution of a tablet and see for yourself.
