If you mean can you use a message from a SNS topic as the trigger for a lambda function, then the answer is yes.
If you mean can you write a lambda function that adds a subscription to an SNS topic then the answer is yes. Towards the bottom are links for the language-specific AWS SDKs. Your Lambda function would need to have the appropriate permissions to be able to add a subscription as well.
