I believe you can via the Site Administrator’s “Languages” form – but it might be less disruptive to check which email templates reference this variable, e.g. by executing the following queries in the DB:
SELECT DISTINCT email_key FROM email_templates_default_data WHERE body LIKE '%{$authorUsername}%';
SELECT DISTINCT email_key FROM email_templates_data WHERE body LIKE '%{$authorUsername}%';
…and then correcting them through the user interface. Just remove that line of text. The reason this change was made is that we’re no longer considering submissions to belong to a single “submitter” account – there may be many authors attached to a submission.

since I prefer to have the standard email templates for 1.2.0, I reloaded the locales (on a test version), but this was indeed quite disruptive, so I copied the two tables (email_templates_default…) from a fresh OMP 1.2.0 version.
This seemed to work. Is this okay or does it cause any incongruity?
