In theory yes. In practical there are several limitations.
One would be, it is immensely expensive.
The process is also just in the experimental stage so possibility of a failure or accident is great.
Moreover one must be really crazy to leave behind his aging relatives and friends and greedily go after immortality.
We can preserve the organs and keep them functioning by lowering the metabolism. But an hundred year sleep or even a decade in sleep will adversely affect the person physiologically and psychologically.
Organs can fail due to a trauma. The years in sleep, you weren't in contact with the world around, so you wouldn't be immune to any new diseases.
A constant care and curating is necessary while an individual is cryogenically preserved.
I'm strictly against it. Because this might cause a mutation in a person and this trait will pass on to future generations who might be able to perform feats like suspended animation and hibernation naturally.
You shouldn't mess up with natural design.
The stronger a light shines the darker are the shadows around it.
As Aditya has mentioned and also as in the Jurassic Park movie, Man should not mess with the supreme being, we may be able to tinker with stalling death or even cheating it in the future but death in man's life cycle was something that we planned or formulated it. It would be a multimillion-dollar program with ethical, and financial issues. Who gets the right to decide who is brought back to life. What is the legal, social status of that person etc?
Then why you want to bring all the dead back?!
I will be back………
