How to list all tables & columns names of a linked-server database in SQL Server?

If it's a regular database, i can simply use this query to get a list of all table names and their column names of the database.

use [my_database_name]
GO

SELECT sys.tables.name AS Table_Name, 
       sys.columns.name AS Column_Name, 
       sys.columns.max_length, 
       (schema_id) As Schema_name

FROM sys.tables
    INNER JOIN sys.columns 
        ON sys.tables.OBJECT_ID=sys.columns.object_id

ORDER BY schema_name, sys.tables.name, sys.columns.name

but right now I need to connect to a linked-server database therefore the 'use' can't be used. Is there another way?

To expand slightly on @scsimon's answer...

The (schema_id) As Schema_name is not very useful, as it's really an ID. To get the list of all tables (and their columns) with actual schema names one can use:

SELECT s.name AS schema_name
      ,t.name AS table_Name
      ,c.name AS column_Name
    --,c.max_length
FROM [SERVER].[DB].sys.tables t
JOIN [SERVER].[DB].sys.schemas s ON t.schema_id = s.schema_id
JOIN [SERVER].[DB].sys.columns c ON t.object_id = c.object_id
--WHERE s.name = 'dbo'
ORDER BY s.name, t.name, c.name
