No. The user gets to control which apps have are on the lock screen. There is no way for an app to force this without the user's permission.

In my application,I want do something every 15 minutes.So I use the timer background task,but the timer trigger required lock screen permission.When first run my application,I call BackgroundExecutionManager::RequestAccessAsync() to requre this permission,but there always pop a dialog.And in windows 8 RP,the samples pre-installed by miscrosoft had this permission,but I don't see them pop this dialog.So I want to konw how they implement and whether I can do.How to implement

There is no way for an app to set this programmatically. The user has control over which apps appear on the lock screen.
Calling BackgroundExecutionManager::RequestAccessAsync() and letting the user choose to allow the app or not is the appropriate thing to do.
When you set up a system image you can preinstall apps and set this state, but I don't know the details beyond that it cannot be done after the fact. For more information about setting up an image see Service a Windows Image . Doing so isn't an app development topic, so please post any questions you have about how to do this in the appropriate Windows 8 Installation, Setup, and Deployment forum on TechNet.

No you cannot.
Please review this document to get a good idea of what you can do with background tasks and their requirements:
