You can, but as I said you should use so called dynamic SQL (EXEC or sp_executesql).
That can slow down the performance.
Something like that:

USE YourDB

CREATE PROCEDURE Test(
       @db_name nvarchar(200) = NULL
       )
AS
  BEGIN
    IF @db_name IS NULL
       SET @db_name = DB_NAME()

    DECLARE @sql nvarchar(max)
    SET @sql = 'SELECT * FROM '+@db_name+'.dbo.SomeTable'
    EXEC sp_executesql @sql
  END

-- and to test it
EXEC Test
EXEC Test @db_name = 'SomeOtherDB'

This is a simple SP, no error handling is included :-)
