Yes. MPEG-4 Part 14 (the MP4 container format) supports any number of objects (i.e.g. video, audio and subtitle streams) and isn't limited to only one stream per content type.

In practice however, you seldom see a video file that has multiple video streams, because the range of applications for this is very limited. I would also advise you not to put multiple video streams into one file, as (a) users don't expect it, many won't know how to switch the video track or not notice there is a second video track at all and (b) many players (soft- and hardware) aren't equipped to play files with multiple video streams and either won't have any option to switch between streams or fail to play the file completely.

It is also more common to use Matroska (.mkv) containers for video files with multiple audio/subtitle streams, but even with those, you rarely see files with more than one video stream.
