The question you are asking is a bit vague. It is not clear whether you are wondering whether Venus can be terraformed, or whether you want to change its morphology as a planet altogether in order to determine whether life could have evolved on it.
If you're talking about terraforming Venus, you will still encounter a lot of obstacles. The main problem with this would be reducing the temperature from over 400 degrees Celsius to something more manageable, along the lines of 50 degrees for instance. However, the scale of this task would be enormous. In addition to this, you will need to alter the atmosphere so that it's not only breathable, but also to make sure that the levels of CO2 and sulfur dioxide are reduced enough so that the greenhouse effect is diminished. Earth itself did go through a similar state back in it's earlier stages as a planet, where volcanic activity resulted in vast amounts of CO2, however the reason it was able to sprout life forms was due to the presence of hydrogen, which is very scarce on the surface of Venus. Therefore, a "successful" terraforming of Venus might just come down to humans creating floating platforms on which they will grow whatever they need for sustenance. However, this is not a viable outcome of a terraforming process and might only be resorted to for research purposes (so those platforms would be mostly inhabited by scientists, like the research bases in Antarctica), or in the extreme case in which the Earth has suffered from a shattering cataclysm and humans have ran out of places to go to.
On the other hand, if what you're asking is whether Venus could be a planet humans could live on if its morphology had been different from the very beginning, then the answer is not so easy to pinpoint. Basically that question would come down to what factors must come together for a planet to support life forms. From then on, the question branches out into several aspects, such as: does the life on that planet have the same living requirements as life on Earth? will there be sentient life on a planet with different conditions? how would these different conditions impact the way those life forms behave and even think? So overall, if it's the second case, your question is a bit vague and you may need to do more looking into it.
