I wonder if a particular philosophical concept/idea/thought experiment has a name. Since I have no idea where to begin with looking it up, can I describe what it's about in a question and expect an answer of "it's called X" or "it doesn't have an official name"?
As unsatisfactory as it might be, I think the only correct answer here is "it depends".
Generally, I would deem it a kind of reference-request. It should be tagged accordingly. Now, whether it is acceptable or not depends a lot on how the question is worded and framed.
If, for example, you know that you ask for an epistemological or an ethical concept, you can use the corresponding vocabulary in the body of the text and the corresponding tags. Ideally, this includes at least negative references like "similar to the concept X of author Y, but different in the aspects A and B insofar as it is rather like...".
If you lack the knowledge to do so, you should point that out in the body of the question and at least aim for tangible examples in order to give a clear idea of what you are thinking of.
The fuzzier and more confused your own thoughts and wordings and the less tangible comparisons or examples to work with, the more probable it becomes that the question will be closed either for the "personal philosophy"-reason, since the community gets the impression that you want to promote your original idea or the "unclear what you are asking"-reason, since the community members genuinely do not understand what you are talking about.
