I am curious, if you pre/append a registered trademark with another word or number could you get in trouble. Like for example would you be able to make a company called "Microsoft 1" or "Sony Stuff" or "Coka Cola Drinks"? Or will they try and sue you for using their trademark inside your name?

Sounds a little sketchy. I wouldn't want to find out the hard way.

Does this help?

i very highly doubt you can.
especially after hearing about a movie company being sued for making shitty movies that look like blockbusters (transmorphers when transformers was new, transmorphers:fall of man when transformers: revenge of the fallen was new). dumb people would buy/rent the shitty b movie and think they bought/rented that blockbuster movie.
