It's possible if the apps package is backwards compatible to earlier Android versions.
Not necessarily. A number of apps can run on earlier versions of Android (ex: Android 2.0--Eclair). It's up to that particular app developer if they want to release an app that supports older Android versions. However, with the number of devices still supporting an older Android OS dwindling, it would be no surprise if a developer may no longer support an older OS.
