you technically can. However, every year will increare the threat of bugs and malware that might steal/expose your private key. Are you sure this wallet is designed to outstand the test of time?
Also, will be your device still operational in 15 years? Will be the substitute device compatiple with Blue Wallet?
The right question, how much you are confidend and risk adverse
Perfect security doesn't exists, and the target for good-enough security always change
Thank you for your answer, what do you recommend?
For a lung run, an hardware wallet is suggested. Also, you are not bound a specific software wallet when using an hardware wallet (the software must still be compatible)
#ColdCard and #SeedSigner are DYI hardwallet, and #BitBox02 is a good commercial wallet if you prefer a more ready-to-go wallet
The choise of the software wallets will be based by the hardwallet choice.
#Sparrow is a good desktop wallet, as #BlueWallet for Android
