No you cannot delete a project but you can "archive it".
Archiving removes your project from a list of active projects and also allows you to bring it back when needed. This is helpful as it allows you not only to save some time if you need to it back, but is also good for record keeping and if let's say your old client for whom you worked let's say 2 years ago needs access to files or documents due to any reason, let's say god forbids there was a fire damage at their house and they need documentation for insurance purposes.
