Some reports available.

• Embeddable.
• Minimal implementation
• Considerable active committers have "M" as their name initials, somehow.
• Some major committers have Matsumoto as their family name, somehow. (They are not relatives)

Can I run mruby on my target?

Arduino

@bovi reported you can run mruby on Arduino Due. http://mruby.sh/201303161453.html

But still we have no reports running on AVR Arduino yet. On the current version of mruby, it is not enough considered to support 16-bits integer architectures. And AVR have small size of RAMs.

You might be interested in some Arduino-pin-compatible boards. Like chipKIT Max32, GR-SAKURA, Enzi, and so on. They boards have high spec 32bits CPUs. You can run mruby on them.

I recommend Arduino Due and/or compatible boards if your wish is using Arduino shields.
