Definitely not. The consequences of overload of a lithium-ion battery are so horrible (they call it 'venting with flame' but they mean 'explosion') that all battery units (in everything) are required to be fitted with a charging circuit that regulates charging current and prevents overcharging. This is also why, if you discharge the Kindle enough, recharging it takes ages -- there's barely enough power to run the charging circuit and it's being paranoid.
