No. See create_toast_table() where the toast table and its index use
the same tablespace as the relation they depend on.
Now, you could use allow_system_table_mods and an ALTER INDEX .. SET
TABLESPACE to change that for the index, but this is a developer
option and you should *not* use that for anything serious:
