Yes, it is feasible to run a version of macOS on that device. The i5 450M with 4GB RAM and a 250GB SSD should support macOS if the hardware meets the system requirements.
It's probably unlikely, though it depends on the laptop's BIOS settings. Running a VM could work, but performance might be affected.
Hackintoshes can be very frustrating. They often malfunction, sometimes losing your files. If it doesn’t work right away, it might fail later after an update. Otherwise, you’ll realize the system isn’t performing well. The VM version seems to be the most reliable option.
In my experience with Opencore, everything is functioning well so far—no issues yet. Just avoid updating right after a new macOS release (especially if you're using a regular Mac). It should remain supported with an iGPU until High Sierra or until the current version, provided your GPU is compatible. For safety, stick to High Sierra and follow the recommended guide at the link you mentioned. Don't try this on your primary machine just because it seems stable for others—what works for one person might not work for you. Also, Hackintosh can be a learning curve that requires some technical understanding of your hardware. Happy experimenting!
