Hi Joseph - yes you can - we use these apps ourselves and plan to maintain them (until such time as someone else ever does)
I notice that BTC Pay link points to btc-core - there are actually two apps (some features in BTC Pay depend on BTC Core):
Bitcoin Core: https://git.nostrdev.com/stuff/cloudron-bitcoin-core/raw/branch/main/CloudronVersions.json
BTC Pay Server: https://git.nostrdev.com/stuff/cloudron-btcpay/raw/branch/main/CloudronVersions.json
One instance of BTC Core can serve all instances of BTC Pay. You can also run BTC Pay without core, or using another instance of core.
