Inclusion debates/"Inferred" names as canonical fact

In The Day of the Doctor, the opening scene showed the sign for Coal Hill Secondary School with "I. Chesterton" as Chairman of the Governors, along with "W. Coburn" as Headmaster. Obviously, most people will associate "I. Chesterton" as the First Doctor's companion, Ian Chesterton. Same for "W. Coburn" and Susan Foreman's classmate Wendy Foreman.

I had edited Ian Chesterton's and Wendy Coburn's wikis to indicate their current status, but I wonder if this was premature, as strictly speaking, one cannot make an in-universe determination that "I. Chesterton" is Ian. It could be "Iris" or "Ishmael" or any other of names that start with an "I". Same for W. Coburn.

Is it possible for the administrators to address this problem? Thanks.
