Sure, for a visit or for business meetings. I as a UK citizen can temporarily visit the US, or Japan, or Thailand on holiday. I could also go to meet my colleagues there, go and sell something, go and buy something, go to a convention, etc. That's counted as "doing business" I can't work there though, unless I have an appropriate visa. Doesn't matter if I'm working remotely for a remote company that doesn't even have a presence in the country, it is still doing work.
