Yes, with some caveats on the defaults and authorization.

The documentation explains the rules for these defaults. Basically, for a folder with a linked Schema to accept a PDF via WebDAV you need the following:

• The PDF must match the mime type for the folder's Multimedia Schema
• The Multimedia Schema's should either have:
  • No required fields
  • Required fields but with defaults set
• Authorization to do the same for that user (Component rights and write on the folder)
• Same-named items will update (create a new major version) an item if it's "editable" (parent item or localized and maybe checked out). Be careful with same-named items elsewhere in the BluePrint though, which will prevent saving in the Content Manager Explorer and WebDAV.

The mandatory setting also affects how the items is saved. For example, if the Schema is set to a non-Multimedia Schema, you could still load the PDF if the Schema is not marked mandatory (it will default to the Default Multimedia Schema).

I think the issue might be the defaults, but check the list to confirm (or post an answer for what worked).
