"Check Wikipedia or any good universities documents. It will be there."

NO!

Not because I care all that much about the specific issue -- whether the name has some specific acronymic meaning, but rather, because you're suggesting that seconday (and very possibly inaccurate) resources should be grounds for ignoring a primary resource, such as Larry Wall's own remarks.

Now, I'll grant that I've not found (in the archives of comp.lang.perl.misc) a statement signed by Wall, nor audio or video of Wall disputing the notion that "perl" or "Perl" is an acronym, nor have I ever had occasion to ask timtoady 'what's the fact?' but the assertions of numerous Perl pioneers (including a good many Monks of Great Tenure; merlyn, tilly (see [Re^5: perl not omnipotent? let's see!), petdance....) are, to me, far more persuasive than sources such as wiki, CS departs at .edus, etc.

Likewise, IMO, the widely reported story that a witty writer invented a backronym to explain his name choice (or as a joke) seems more plausible than that he departed so radically from the common use of

• pedestrian acronyms (COBOL, BASIC, etc.),
• personal initials (awk, for example)
• or personal names with historic CS significance (ADA)

as denominators for computer languages.
