"Yes" doesn't really cover all the situations. Google has attempted to make code you write for 1.5 (code level 3) or 1.6 (code level 4) forwards compatible with Android 2.0 (code level 5). This works "mostly" but you may have to make a few tweaks.
In my case when they went from 1.6 they broke almost every single one of my widgets that I have written due to a parameter I was using in my provider.xml file that they changed. I had to make a small modification to all of them to keep it compatible with 1.5 but also forwards compatible with 1.6 and 2.0. Another fine example is with the higher screen resolutions. If you made the mistake of using of a font size of say "12pt" in 1.5, thats going to look like crap on a Droid with a higher resolution. I had to change a lot of stuff like that to support across the board screen resolutions. Your best bet right now is to write your application using SDK level 3 (Android 1.5) and then test it in an AVD emulator for 1.5, 1.6, and 2.0. The reason you want to still be supporting 1.5 is because ALL of the HTC Hero line of phones are still running 1.5. This includes the Hero, the Eris, the European Hero, etc. There are also versions of phones in other countries where the carrier did not push out 1.6 to it's customers. Good luck!
