Can I multiply the Pearson Coefficients by 10 to make impact? I have extracted the Pearson correlation Coefficients between the labels and features. Can I multiply the final correlation score for each score by 10 to make it higher to investigate it with machine learning?

SURE
That's a conversion of units, analogous to expressing in decimeters instead of meters.
However, I have my doubts that this would make a difference. When it might matter is if you need to present to an audience that would rather see percentages (so multiplying by $100\%$, not just $10$) than decimal numbers less than $1$ (e.g., $26\%$ instead of $0.26$).
