Yes. See remarks below.

Given that I think you mean 'but user1 and user2 will not', that is

No. It won't break anything. Putting @sales in any *_these_nonmembers
field of the everyone list is just the same as individually listing
all the member addresses of the sales list including the address
'teamleaders at example.com'. At the point of processing the nonmember
post, teamleaders at example.com is just another address which may or may
not be the sender of the post. It probably won't match, and it won't
be expanded in any way.

Note that Mailman doesn't do well with lists that have a mixture of
real users and other lists as members. If you declare the list as an
umbrella list, then e.g. member user3 at example.com may not be able to
get a password reminder as it will be sent to user3-owner at example.com.
If it's not an umbrella list, then anyone can go to the options login
page for e.g. teamleaders at example.com and request a reminder which
will be posted to the teamleaders list.
