Short answer: No, the concrete blocks are too heavy.
I asked the question you reference and while the picture isn't my own, the concrete blocks I have are exactly the same. The blocks themselves are fantastic, easy to mow over and wide enough to keep out my invasive grass (most of the time) - buffalo.
This is a great DIY task and an excellent improvement, mine look great. But unless you're a weight lifter, you would need at least 2 people. I'm a big, (I like to think) strong guy and those block are HEAVY! I would say they're around 40-50kg (100lb) and about 100 cm (40in) long. I broke a shovel trying to dig out out, snapped the handle in half! I moved 4 and it just about killed me.
Do yourself a favour and get a mate to help you out.
Good thick gloves are a must and a mattock helped me.
