Yes. There is a difference.
Checkpoints are a feature where buffers are flushed and updates are guaranteed to be written to disk, and for some implementations, logged. Checkpointing is usually intricately involved with recovery features of a DBMS. A savepoint is a nested transaction concept which allows developers to have control on how much of a transaction is rolled back on error or failure. It gives more flexibility than an all-or-nothing transaction.
