It really depends on what you mean by "clear" if it means to make a transparent colorless beverage I´ll say no, if you mean to make a beer that haves whatever color the style is but clear yes you can, and there is many ways of achiving this, temperature, finnings, filtration etc etc
you can with properly designed filters. Its called "clear malt beverage." All you need is a filter with a small enough diameter membrane. Homebrew shops sell filters that leave beer with a "polish" i.e. very bright, but also remove color. Something a few grades smaller in filter screen diameter would probably remove all color.
