You can but it's dangerous. You want validation from your idea to come from who are truly likely to be your customers. Also, the setting creates more bias to answers then what you'd want in a good customer development process.

This is a great place to ask about how to go about good customer development and I'd be happy to help in that area. Look at my other answers around these topics as they might be helpful to this question as well

You certainly can:
1- check other similar questions related to your idea
2- ask experts how to plan your customer segmentation and validation
3-look for experts that can help you understand the data you have gathered via research and/or customer validation.

These are obvious suggestions but you want to leverage experience and expertise when it comes to validation. Do make sure though to have done your homework and enough research beforehand. You don't want to be ready for a pivot right after a call.

Good luck and contact if needed.
