As I understand it, Chromebooks are meant more for strictly web-based applications rather than traditional binary applications. It does look like you can buy Chromebooks with either an ARM processor (which isn't supported by BYOND) or an Intel processor, but considering that Chrome OS is Linux-based, you'd most certainly have to do some sort of virtualization if you wanted to actually play games (if you can even install something like BYOND on it to begin with).
