Here's what I think:

1.shake up - to disturb or rouse (people) so as to make them more energetic. Fine. Without 'up', it only means to move them physically, usually to wake them.

2. shake somebody up - to surprise somebody and make them think about something in a different way, become more active, etc. Shaken up by the early goal against them, the team began to fight back.
shake something up. Fine; possible without 'up'.
to make important changes in an organization, a profession, etc. in order to make it more efficient. The whole industry needs shaking up. Fine; not likely without 'up'
