Short Answer: 'No'.
NOT according to the current "Knowledge Article" in 'FamilySearch':
How do I create a free FamilySearch account?
Published: 20 April 2020
[ Really, the update (ie. 'revamp') of the "Help" facility, rather than the article ]
Where it states:
Age limits — You must be at least 13 years old to create an account. Children ages 8 to 12 can create an account with parental permission.
NOTHING has changed.
I hope this helps.
ps: Stay tuned, you never know, "Knowledge Articles" in 'FamilySearch' are notoriously behind the times (ie. 'Out of Date' to actual changes) ...
