No. It isn't required. The Kindle can charge off a computer USB port and that follows the USB standard of having a maximum of 500mA available. The Kindle quick start guide even mentions that not all Kindle configurations come with a charger so in those cases, the user would only have the ability to charge via a computer. It may charge faster if it has more than 500mA but it isn't required.
The Kindle successfully charges off the charger for my Android phone. I've not tried it yet with the Apple mains chargers for their iPods/iPhones.
The reason why not all chargers work is how they're wired. There are two wires for power and two for data in a USB connection. Most new devices don't just look at the power connections to see if they should charge. They'll test the USB data lines to see if there is a specific voltage or resistance on them first. If that voltage is wrong or the resistance is wrong then the device will refuse to charge.

The Kindle doesn't appear to have that ability. It is either in charging + USB drive mode or just charging mode.
