Yes. The particular questions you link to don't demonstrate this well, but if they were phrased differently, then certainly they would require a different audience.
For instance, on SF I'd prefer to see:
"We have users across several continents, nations, with different equipment and resources. We'd like a company-wide policy on cleaning your display devices that will not only work on CRTs, LCDs with glossy finishes, LCDs with matte finishes, conference room TVs, phone displays, etc, but use commonly (and legally!) available, inexpensive solvents and cleaning materials so that we can reduce tech support issues and have a single, cohesive, and widely applicable display cleaning policy."
This would clearly be in the realm of IT, whereas the more general "how do I clean my monitor" questions might well be relegated to SU.
Note that the questions are still similar, but they have a different answer and audience, and require a different point of view.
