You can't update multiple tables in one statement. Instead of that you can use a transaction to make sure that two Update statements are treated atomically.
Eg:
DECLARE @MyTable TABLE (id int);
BEGIN TRANSACTION
UPDATE Table1
SET Table1.Name = 'Test'
OUTPUT INSERTED.id INTO @MyTable
WHERE T1.field = 'Your Value';
UPDATE Table2
SET Table2.YourColumnName = 'Your Value'
FROM Table2
JOIN @MyTable m on m.id = Table2.id;
 
COMMIT;
