It is not possible
this is one comment from support
"The list name is decoupled from the object name as soon as it's created." This is how it's implemented, not how it's "expected". From the users' point of view, there is no second chance to modify that list name, which means that they cannot make any typo, and they can not change idea later. That's not very user-friendly.
Using below query will help but the support did not approve it saying this is as per the design and not a bug.
update cmn_captions_nls set name='updated name' where name='old name' and
language_code='en'
and table_name in('CMN_PAGES', 'CMN_PORTLETS','CMN_ACTIONS',
'CMN_MEU_ITEMS','CMN_PAGES')
