Nope. ADE is a specific app that runs on Windows and OSX. It does not run on ereaders.

Feel free to check with reading app developers (I did). I was told that what Adobe licenses to app developers and ereader makers is the DRM decryption components. They do not provide the rendering engine (which displays text).
