Is the term ubiquitous enough these days that someone with limited software exposure would understand what it is intuitively?
The term Wizard was most prevalent in the early Millenium, but even then mostly more advanced users will know what it is. Someone with limited tech exposure ("noob's with little to no experience beyond email and browsing") will not know what a wizard is because the term doesn't relate to any real world concepts.
The Microsoft Manual of Style for Technical Publications (Version 3.0) urges technical writers to refer to these assistants as "wizards" and to use lowercase letters. In countries where the concept of wizard does not convey the idea of helpfulness or is offensive (via the suggestion that actual magic is being used), the manual suggests using the term "assistant" instead.
A Wizard is also often associated with multi-step installations and operations not introductions to how to use the software.
Ultimately, be very clear and specific on what you are walking the user through. If it's a tutorial, use "Follow our Tutorial" if it's a long ecommerce check out, use "Pay for your Order".
Most users with low technical experience I've encountered shun away from wizards because they usually lead to more difficult questions and the fear of clicking wrongly especially with software installs will increase their avoidance.
I gave a +1 to Oleg for suggesting "Tour" or "Guide" which is great if the tool is introducing the software and it's the user's first time going through.
