As far I know, No, you can't share the mdf file across the intranet or internet. If you want to access the same database over a network then you have to install SQL Server in one of your system which will behave as a server.

Well you need to not use AttachDbFilename when you connect. That is change your connection string to a more standard one.

Then enable network access to your database

You have to decide if you want to use integrated security, in which case connecting user will have to have rights for the database, or perhap make an application user which just goes into the connection string using MSSQL server authentication and which can be shared.
