Yea you can totally use Lambda for that. For example you can schedule triggers in Cloudwatch that runs a lambda at intervals to do whatever you need, for example generate a pdf and put it on s3 where you or your users can access it directly.

+1 for CloudWatch scheduled triggers. We used to have a few EC2 worker instances running cron jobs, but since switching to CW scheduled triggers and Lambda, have managed to save a bunch of $$$ on running instances that were doing menial work.
