What is the difference between Review and Analysis in DO-178C?
No they are not the same.  

Reviews are qualitative. They typically compare the artifact being reviewed to a standard using a checklist.  

Analyses are quantitative. They could be functional analysis, data flow analysis, timing analysis, or other evaluation of the software artifact.  

From DO-178C:


  6.3 Software Reviews and Analyses  
  
  Reviews and analyses are applied to the outputs of the software
  development processes. One distinction between reviews and analyses is
  that analyses provide repeatable evidence of correctness and reviews
  provide a qualitative assessment of correctness. A review may consist
  of an inspection of an output of a process guided by a checklist or
  similar aid. An analysis may examine in detail the functionality,
  performance,  traceability, and safety implications of a software
  component, and its relationship to other components within the system
  or equipment.
