Yes, as long as you've purchased a convertible term life insurance policy.
Keep in mind that convertible term life insurance usually has a conversion deadline, which is the date by which you must convert. And when you do convert your policy, you can expect your premiums to increase as you'll have permanent and not term insurance.
The new premiums will be based on your age; this may be either your current age or the age at the time you took out the policy (an original date conversion).
If you convert to your original age, you'll have to pay all back premiums and interest when you convert. The good news is that you won't have to prove your insurability (e.g., through medical exams) at the time of conversion.
